MATLAB: In an assignment A(I) = B, the number of elements in B and I must be the same.

??? in an assignment a(i) = bthe number of elements in b and i must be the same.

Hi ,

I am new to MATLAB, I need help with this problem please help!

I'm trying to do this operation.

A is 256 * 1 double

B is 18 * 1 complex double

I am trying to do

A (17: 240) = B;

But I am getting this error! what might be the reason?

"In assignment A (I) = B, the number of elements in B and I must be the same."

Your:

A(17:240) % is a vector of 224 elements ((240-17+1)x1)

while

B % is a vector  of 18 elements (18x1)

that's why you are getting the error

I assume that A is either not initialized, or it is initialized as a numeric array. An element of a numeric array can only store one numeric value.

You might be able to use a cell array, which can store values of mixed types. In that case your syntax might be

A = cell(14,1);
for k=1:14
    A{k}=TrajSimilarity(1,k).aLongestString;
end

Notice the use of {} instead of () to access the contents of each cell.

if abs(a-b)<0.0001
    disp('LHS==RHS')
end
