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."

"But I am getting this error! what might be the reason?"
You are trying to assign 18 elements to 224 elements.
On the LHS you use indexing to refer to 224 elements of the array A.
On the RHS you have an array with 18 elements.
Given that the RHS only has 18 elements, what do you expect the remaining 206 elements to be filled with? As the error message states, both the LHS and the RHS need to refer to the same number of elements.

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
