assigning output of a for loop to an array

i want to put the 6 values of W into an array but i cant sry fr the silly question

E = 10;
Rt = 1000;
Rm = 0.01;
for Ri = (0:200:100)
   W = error_calculation (Ri,Rt,Rm,E);
end

W(Ri) = error_calculation (Ri,Rt,Rm,E);

will put the values into an array, assuming the output of error_calculation is a scalar. If not then you need to use W{Ri} for a cell array or you can assign to a multi-dimensional numerical array if the size of the result is always the same.

Though you should presize this before the loop.

I assume this was a typo:

for Ri = (0:200:100)

and you meant to loop up to 1000 to get your 6 values.

W = zeros( 1, 6 )

works for presizing, although I don't like hard-coding an assumption in two independent places so I would maybe create the 0:200:1000 vector first and use numel to get its size to presize the result.
