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