Hi everyone,

I'm trying to rewrite an equation to be able to solve it as a linear problem. The equation is:

$\displaystyle P_1 H H^{-1} X_1 = P_2 X_2$,

where $\displaystyle P_1$ and $\displaystyle P_2$ are 3mx4 matrices, $\displaystyle X_1$ and $\displaystyle X_2$ are 4xn matrices and $\displaystyle H$ is a 4x4 matrix.

I rewrote this equation to:

$\displaystyle P_1 H X_1 = P_2 H X_2$

Now I want to write this equation in the form:

$\displaystyle A H = 0$

Can anyone help me with this? How can I rearrange the formula to the above format?

Thanks,

Tim
