MATLAB: Unable to perform assignment because the left and right sides have a different number of elements.

forloop

Best Answer

In your expression, the left hand side is just a scalar (only has one element) but you are trying to assign a length 4 column vector to it. This doesn't make sense.

It would be much simpler just to make your "100 sets of 4 random #'s" using one line in MATLAB

D = normrnd(50,10,[4,100])

This will produce a 4 by 100 matrix, where each column is a set of 4 random numbers

MATLAB: Unable to perform assignment because the left and right sides have a different number of elements.

The error is clear; when you try to save more number of elements in an array which initialized with less number.

Example:

A = zeros (1.10);
A (1) = rand;
A (2) = rand (1,2);  % this will throw error, you have to save only one element but you are saving two elements

In your case, check what is dimension of RHS created and what dimension LHS is initialized.

s_code = cell(100,1); 
for i=1:100                  
  s_code1{i}=strcat({s_code{2*i-1},s_code{2*i}); 
end
