plotting IRF when structural errors have been manually recovered in a VAR

The inbuilt IRF function does a choleksy decomposition to recover the structural shocks and hence plot IRF. I have recovered my matrix of structural shocks for Blanchard -Quah(1989). How do i plot the IRF?

YOu want to plot a matrix? Have a look on pcolor, surf

No, my doubt is this: when we are plotting the IRF for a VAR, matlab does a cholesky decomposition to recover the structural errors and plots the IRF. There are other ways to recover the structural errors. Let us say that I have manually recovered the structural errors and would like to plot the IRF in accordance with the manually recovered errors and not the errors recovered by the IRF function.
