Custom Sort Range - range

Just need to know how can I get the following code not to get me a type mismatch error. The last line which is commented out works but when i replace the Range("B2:B2000") with f it gives me a type mismatch error. Reason why I am not just using the last line instead since it works is because what if column B becomes Column C if i insert a new column in Column B. Is there something else that I need to add to the f to make it work?
f = Application.WorksheetFunction.Match("PCR No.", Range("A1:AZ1"), 0)
ActiveWorkbook.Worksheets("3. PMO Internal View").Sort.SortFields.Add Key:=Cells(1, f)
ActiveWorkbook.Worksheets("3. PMO Internal View").Sort.SortFields.Clear
ActiveWorkbook.Worksheets("3. PMO Internal View").Sort.SortFields.Add Key:= _
f, SortOn:=xlSortOnValues, Order:=xlAscending, DataOption:=xlSortNormal
'Range("B2:B2000"), SortOn:=xlSortOnValues, Order:=xlAscending, DataOption:=xlSortNormal

How can I convert this select statement to functional form?

I am having a couple of issues to put this in a functional format.
select from tableName where i=fby[(last;i);([]column_one;column_two)]
This is what I got:
?[tableName;fby;enlist(=;`i;(enlist;last;`i);(+:;(!;enlist`column_one`column_two;(enlist;`column_one;`column_two))));0b;()]
but I get a type error.
Any suggestions?
Consider using the following function, adjust from the buildQuery function given in the whitepaper on Parse Trees. This is a pretty useful tool for quickly developing in q, this version is an improvement on that given in the linked whitepaper, having been extended to handle updates by reference (i.e., update x:3 from `tab)
\c 30 200
tidy:{ssr/[;("\"~~";"~~\"");("";"")] $[","=first x;1_x;x]};
strBrk:{y,(";" sv x),z};
//replace k representation with equivalent q keyword
kreplace:{[x] $[`=qval:.q?x;x;"~~",string[qval],"~~"]};
funcK:{$[0=t:type x;.z.s each x;t<100h;x;kreplace x]};
//replace eg ,`FD`ABC`DEF with "enlist`FD`ABC`DEF"
ereplace:{"~~enlist",(.Q.s1 first x),"~~"};
ereptest:{((0=type x) & (1=count x) & (11=type first x)) | ((11=type x)&(1=count x))};
funcEn:{$[ereptest x;ereplace x;0=type x;.z.s each x;x]};
basic:{tidy .Q.s1 funcK funcEn x};
addbraks:{"(",x,")"};
//where clause needs to be a list of where clauses, so if only one whereclause need to enlist.
stringify:{$[(0=type x) & 1=count x;"enlist ";""],basic x};
//if a dictionary apply to both, keys and values
ab:{$[(0=count x) | -1=type x;.Q.s1 x;99=type x;(addbraks stringify key x),"!",stringify value x;stringify x]};
inner:{[x]
idxs:2 3 4 5 6 inter ainds:til count x;
x:#[x;idxs;'[ab;eval]];
if[6 in idxs;x[6]:ssr/[;("hopen";"hclose");("iasc";"idesc")] x[6]];
//for select statements within select statements
//This line has been adjusted
x[1]:$[-11=type x 1;x 1;$[11h=type x 1;[idxs,:1;"`",string first x 1];[idxs,:1;.z.s x 1]]];
x:#[x;ainds except idxs;string];
x[0],strBrk[1_x;"[";"]"]
};
buildSelect:{[x]
inner parse x
};
We can use this to create the functional query that will work
q)n:1000
q)tab:([]sym:n?`3;col1:n?100.0;col2:n?10.0)
q)buildSelect "select from tab where i=fby[(last;i);([]col1;col2)]"
"?[tab;enlist (=;`i;(fby;(enlist;last;`i);(flip;(lsq;enlist`col1`col2;(enlist;`col1;`col2)))));0b;()]"
So we have the following as the functional form
?[tab;enlist (=;`i;(fby;(enlist;last;`i);(flip;(lsq;enlist`col1`col2;(enlist;`col1;`col2)))));0b;()]
// Applying this
q)?[tab;enlist (=;`i;(fby;(enlist;last;`i);(flip;(lsq;enlist`col1`col2;(enlist;`col1;`col2)))));0b;()]
sym col1 col2

Glad you were able to fix your problem with converting your query to functional form.
Generally it is the case that when you use parse with a fby in your statement, q will convert this function into its k definition. Usually you should just be able to replace this k code with the q function itself (i.e. change (k){stuff} to fby) and this should run properly when turning the query into functional form.
Additionally, if you check out https://code.kx.com/v2/wp/parse-trees/ it goes into more detail about parse trees and functional form. Additionally, it contains a script called buildQuery which will return the functional form of the query of interest as a string which can be quite handy and save time when a functional form is complex.
I actually got it myself ->
?[tableName;((=;`i;(fby;(enlist;last;`i);(+:;(!;enlist`column_one`column_two;(enlist;`column_one;`column_two)))));(in;`venue;enlist`venueone`venuetwo));0b;()]
The issues was a () missing from the statement. Works fine now.
**if someone wants to add a more detailed explanation on how manual parse trees are built and how the generic (k){} function can be replaced with the actual function in q feel free to add your answer and I'll accept and upvote it

Issue: Confusing: Index must be a positive integer or logical

I've got such a problem using MATLAB:
I wrote this function:
function E = f(x, lamda)
E = 1 - exp(-lamda * x);
end
When I write: Prob = f(1000, lamda); where lamda = 3.4274e-004
I get this error:
??? Attempted to access f(1000,0.000341565); index must be a positive integer or logical.
I understand that it requires a positive integer, but why ? I need lamda to be real. What's the problem here ? Can you, please, tell me where I'm wrong?
You have a function f and a variable f declared at the same time. Do clear f; then try your code again. What's happening here is that the variable declaration takes precedence over your function and so doing f would try and access the variable f first.
If you're using f as a variable somewhere and can't change this, then rename your function to be something other than f... perhaps... comp or something. Once you do this, make sure you change your file name so that it's called comp.m, then do:
Prob = comp(1000, lamda);
Your error message indicates that there is a variable called f in your workspace and matlab thinks you are trying to access its elements. Remove the variable f with clear('f') or rename the function to something else and you should be fine.

MatLab Map - Specified Key Type Not Matching Required

I'm attempting to make a program (for homework) which reads in a file, and then counts the number of times each word is used. For tackling the issue efficiently, I've decided to map all unique words to keys, and then increment the key value each time the word comes up.
function [] = problem2
file_open = fopen('austen.txt');
complete_string = textscan(file_open, '%s');
numel(complete_string{1,1})
unique_words = unique(complete_string{1,1});
length(unique_words);
frequency = zeros(numel(unique_words), 1);
found_frequency = containers.Map(unique_words, frequency);
for i=1:numel(complete_string{1,1})
found_frequency(complete_string{1,1}(i)) = found_frequency(complete_string{1,1}(i))+1;
end
fclose(file_open)
Sadly, this code does not work. When the line comes up to increment, I receive an error stating that "specified key type does not match the type expected for this container", which makes no sense to me - I'm using strings as the keys. Any ideas as to why I'm receiving this error?
The issue was in the use of Cell type - complete_String{1,1}(i) would actually return a Cell rather than a String (per spec, though). Wrapped it in char(*) and it worked fine.

Operating on internal tables with header line

I have a question about internal tables' header line.
I assigned some values into in_table1 and then try to add a record with APPEND command into in_table2 in the following block of code.
But I cannot see the record that I have appended into in_table2.
Is this because of the header line of in_table2?
If yes, how can I see the records anyway?

First of all, you should not use internal tables with header anymore.
Second of all, if you really have to do it, here is some solution.
The header in_table2 is of course empty in your case. You have to loop through the table to print it out. For example like this.
LOOP AT in_table2. "here in_table2 means table (an internal table)
WRITE / in_table2. "here in_table2 means the header of the table (a structure)
ENDLOOP.
Internal tables with headers should not be used exactly because of this confusion. Looks like you got confused exactly in such way. The meaning of in_table2 is ambiguous and depends on the context.
Better use field symbols for looping and appending.
FIELD-SYMBOLS: <fs_for_loop> LIKE LINE OF in_table2[].
LOOP AT in_table2[] ASSIGNING <fs_for_loop>.
WRITE / <fs_for_loop>.
ENDLOOP.

MATLAB: If Statement inside loop is not executing, nor printing to the screen

So, we are trying to execute the following code. The two if statements are executing, however, the inside if statements are failing to execute (we verified this by not suppressing the output). Is there a reason why? Or are we just not able to reach this state?
Specifications
The input is as follows: v is a vector of int values and c is a integer. c must be less than or equal to one of the values within v
The problem that we are trying to solve with this algorithm is as follows:
Given a cash register, how does one make change such that the fewest coins
possible are returned to the customer?
Ex: Input: v = [1, 10, 25, 50], c = 40. Output O = [5, 1, 1, 0]
We are just looking for not a better solution but more of a reason why that portion of the code is not executing.
function O = changeGreedy(v,c)
O = zeros(size(v,1), size(v,2));
for v_item = 1:size(v,2)
%locate largest term
l_v_item = 1
for temp = 2:size(v,2)
if v(l_v_item) < v(temp)
l_v_item = temp
end
end
%"Items inside if statement are not executing"
if (c > v(l_v_item))
v(l_v_item) = -1 %"Not executing"
else
O(l_v_item) = idivide(c, v(l_v_item)) %"Not executing"
c = mod(c, v(l_v_item)) %"Not executing"
end
end
If c or v are not integers, i.e. class(c) evaluates to double, then I get the following error message
??? Error using ==> idivide>idivide_check at 66
At least one argument must belong to an integer class.
Error in ==> idivide at 42
idivide_check(a,b);
and the program stops executing. Thus, the inside of the second statement never executes. In contrast, if, say, c is an integer, for example of class uint8, everything executes just fine.
Also: what are you actually trying to achieve with this code?
Try to do this operation on your input data:
v = int32([1, 10, 25, 50]), c = int32(40)
and run again, at least some portions of your code will execute. There is an error raised by idivide, which apparently you missed:
??? Error using ==> idivide>idivide_check at 67
At least one argument must belong to an integer class.
Error in ==> idivide at 42
idivide_check(a,b);
Indeed, idivide seems to require that you have actual integer input data (that is, class(c) and class(v) both evaluate to an integer type, such as int32).
