Programming and Data Types

Applying Functions and Operators

Use indexing to apply functions and operators to the contents of cells. For example, use content indexing to call a function with the contents of a single cell as an argument.

A{1,1} = [1 2; 3 4];
A{1,2} = randn(3,3);
A{1,3} = 1:5;
B = sum(A{1,1})

B =

     4     6

To apply a function to several cells of a non-nested cell array, use a loop.

for i = 1:length(A)
    M{i} = sum(A{1,i});
end
