Extracting data from a cell in Matlab - matlab

Question

Suppose I have C cell as I mentioned below:
C =
[31, 17] [57, 17] [83, 17] [109, 17] [135, 17]
[31, 33] [57, 33] [83, 33] [109, 33] [135, 33]
[31, 49] [57, 49] [83, 49] [109, 49] [135, 49]
[31, 65] [57, 65] [83, 65] [109, 65] [135, 65]
[31, 81] [57, 81] [83, 81] [109, 81] [135, 81]
[31, 97] [57, 97] [83, 97] [109, 97] [135, 97]
[31, 113] [57, 113] [83, 113] [109, 113] [135, 113]
[31, 129] [57, 129] [83, 129] [109, 129] [135, 129]
[31, 145] [57, 145] [83, 145] [109, 145] [135, 145]
[31, 161] [57, 161] [83, 161] [109, 161] [135, 161]
[31, 177] [57, 177] [83, 177] [109, 177] [135, 177]
Now I want to extracting all of its data in new matrix-es
like this:
C11 = ([31,17] [57,17]; [31,33] [57,33])
C12 = ([57,17] [83,17]; [57,33] [83,33])
C13 = ([83,17] [109,17]; [83,33] [109,33])
C14 = ([109,17] [135,17]; [109,33] [135,33])
C21 = ([31,33] [57,33]; [31,49] [57,49])
C22 = ([57,33] [83,33]; [57,49] [83,49])
C23 = ([83,33] [109,33]; [83,49] [109,49])
....... ........ ....... ...... ..
C104 = ([109,161] [135,161]; [109,177] [109,177])
How can do that in Matlab?

Answer 1

Just use array subscripting with round parentheses. For instance ,C12 would be computed like so:
>> C12(1:2, 2:3)
ans =
{ [ 57 17 ] [ 83 17 ] }
{ [ 57 33 ] [ 83 33 ] }
You can do a for loop to iterate over your cell array and extract the necessary cells one by one, and store each one in a different variable. However, all the data is already stored C, so why duplicate it? I suggest that you keep everything in a cell array and extract matrices only when you need them.
