how to write vector with different length in a file? - matlab

Question

I have 7 vectors (L_mean_argil, L_Min_argil, L_Max_argil, R_mean_argil, R_Min_argil, R_Max_argil, Zero_argil) with different lengths and I want to create a .sae file with all the vectors. Here my code:
fileID = fopen('BN_for_prediciting_zeros_argilliti_v1.sae','w');
fprintf(fileID,'L_mean_argil, L_Min_argil, L_Max_argil, R_mean_argil, R_Min_argil, R_Max_argil, Zero_argil\n');
fprintf(fileID,'%6.4f, %6.4f, %6.4f, %6.4f, %6.4f, %6.4f, %6.4f \n', L_mean_argil, L_Min_argil, L_Max_argil, R_mean_argil, R_Min_argil, R_Max_argil, Zero_argil');
fclose(fileID);
It doesn't write vectors properly. Someone can help me?
I expect this:
L_mean_argil(1) L_Min_argil(1) ... Zero_argil(1)
L_mean_argil(2) L_Min_argil(2) ... Zero_argil(2)
...
L_mean_argil(end) L_Min_argil(end) ... Zero_argil(end)
But in the final part of some vectors, there will be empty cells associated to others with values

Answer 1

Here is an answer assuming you want to leave blanks in rows with missing data.
%Sample Data all of different lengths
a = 1:4;
b = (1:6)+1;
c = (1:5)+2;
%Get max length
maxSize = max([numel(a) numel(b) numel(c)]);
%Convert to Cell array if it isn't already
a = num2cell(a,1);
b = num2cell(b,1);
c = num2cell(c,1);
%Initialize a cell to hold everything. Init to the max size
output = cell(3,maxSize);
output(1,1:numel(a)) = a;
output(2,1:numel(b)) = b;
output(3,1:numel(c)) = c;
%Print...
fprintf('%0.1f,%0.1f,%0.1f\n',output{:})
Results in the this:
1.0,2.0,3.0
2.0,3.0,4.0
3.0,4.0,5.0
4.0,5.0,6.0
,6.0,7.0
,7.0,
