using specific columns from a constant

hello all,

I have a rather large matrix (99226,40) that I load to a .mdl via From Workspace and use it as a constant input to a product. Is there a way where I can select how many of the columns I can use?

i.e. I want to see the product of X*matrix(:,1:9);

X is also a constant.

Thank you in advance

In your constant block set the value to

matrix(:,1:9)

Use another constant block for X
