Why am i getting the : errir using inv ,Matrix must be square?

Hello ,

i have a created a toeplitz matrix H which is 12x8 .I want to run the command:

y=inv(H) but the compiler says : Error using inv Matrix must be square

Do you know where is the problem?

[James Tursa]

The problem is that the inverse of a non-square matrix is not defined. What would you be using inv(H) for downstream in your code?

I want to find the equalizer of zero forcing fk :

So in order to find the fk matrix i need to multiply g matrix with the inverse of toeplitz matrix h

[KALYAN ACHARJYA]

Is "h" is the square matrix?

As James Tursa said, inv(H) is not defined when H is not square. If you have the matrix H and the rhs g, simply use

f = H\g;

Or in some cases pinv() can be used instead of inv()
