# Homework Help: Solving simple equation in Matlab

### Inertigratus

1. The problem statement, all variables and given/known data
I want to solve for H(f).
I know that f is supposed to be constant.
X(f) and Y(f) are both column vectors with a total of 32768 rows.

2. Relevant equations
H(f)X(f) = Y(f)

3. The attempt at a solution
I tried dividing, H(f) = Y(f)/X(f) but got an "Out of Memory" error.
It's not a matrix so I can't find an inverse too.
Any ideas?
I think H(f) is supposed to be a column vector as well, but since f is supposed to be constant then all entries will be the same.
Nevermind, It's simply elementwise division, but something's wrong...

Hi,

To perform element-wise division in Matlab (which I think is what you're trying to do), you must precede the forward slash with a full stop.

I.e. replace '/' with './'

Matlab performs matrix right division when the operator '/' is used, and I'm not entirely sure what that entails for two column vectors.
