MATLAB: How to create a matrix from specific Cell array elements

cell arraymatrix

I have a cell array (dimensions 21×8) and i need to get the values (1,1 – 1,2 – 2,1 – 2,2) and create a matrix, each element on the cell array is a vector of 10 elements. Which is the best way to solve this? Thank you in advance

Where C is your cell array:

 cell2mat(C(1:2,1:2))

MATLAB: How to sum specific matrix elements

Try this:

rowsToSum = A(:, 2) < 0;
theSum = sum(A(rowsToSum, 1)); % Sum first column where second column is negative.

MATLAB: How to perform circshift on specific elements

You are overwriting the original array, instead of using circshift on the partial array.

A = [1 2 3 4; 5 6 7 8; 9 10 11 12];
L = false(size(A));
L(1:2:end, 2:3) = true;
A_temp = A(L);
A_temp = circshift(A_temp, [0 -1]);
A(L) = A_temp;
%Or with more compact notation:
A = [1 2 3 4; 5 6 7 8; 9 10 11 12];
A(1:2:end, 2:3) = circshift(A(1:2:end, 2:3), [0 -1]);
disp(A)
     1     3     2     4
     5     6     7     8
     9    11    10    12
