assign value to variable from cell of array in matlab

To assign a value from a specific cell of an array to a variable in Matlab, you first need to access the cell using the indices of the row and column that contain the desired value. You can then assign the value to a variable using the equal sign.

Here is an example:

main.m
A = [1 2; 3 4];
% Access the value in the second row, first column:
val = A(2, 1);
% Assign the value to a variable:
my_var = val;
% Display the value of the variable:
disp(my_var); % Output: 3
194 chars
8 lines

In this example, A is a 2-by-2 matrix. To access the value in the second row, first column, we use the indices (2, 1). We assign this value to the variable val, and then assign val to my_var.

Note that you can also assign a value to a specific cell of an array using the same syntax:

main.m
A(2, 1) = 5;
disp(A); % Output: [1 2; 5 4]
43 chars
3 lines

This assigns the value 5 to the second row, first column of A.
