MATLAB: Fill matrix from cell matrix

Question

HELLO,

I have a cell matrix B (1 * 67 cell), each cell contains a matrix of type N * N C is a cell matrix of type 1 * 67 cell, each cell contains a matrix of type 1 * M I want to fill A from B by respecting the column number indicated in C

for j=1:67
A{j}=B{j}(:,C);
end
error Function 'subsindex' is not defined for values of class 'cell

EXEMPLE for a cell of the matrix

B'= 
1 5 3 4 5 6 9 1
4 5 6 7 8 9 8 9
7 8 9 6 5 4 1 2
9 8 7 6 5 4 5 6
1 2 3 4 5 6 1 2
9 8 7 6 5 4 2 3
7 5 8 8 6 9 7 8
C'= 2 7 8
So A'=
5 9 1
5 8 9
8 1 2
8 5 6
2 1 2
8 2 3
5 7 8

I'm trying to convert the cell matrix into a table matrix

Tabl= cell2table(B);
Ta = cell2table(C);
A=Tabl(:,Ta);
error using "Table variable subscripts must be real positive integers, logicals, strings, or cell arrays of strings."

Do you have an idea

thank you in advance

Answer 1

You need to index into Cell array C.

A{j} = B{j}(:, C{j});

In your code, to used C as the index itself.
