Inputs must be 2-D, or at least one input must be scalar

Hello

I want to write the following codes in MATLAB, but I encounter a problem like as following

[H1,c,ms,path]=mytopo(topo);
[l,r,route]=size(H1);
maxc=max(c);  
z1=(maxc/r)*ones(r,1); 
y=H1*z1;

Note: H1 is 3d matrix. When I want to run the program, the following error occurs:

Error using

Inputs must be 2-D, or at least one input must be scalar.

To compute elementwise TIMES, use TIMES (.*) instead.

Error in Dtrump

y=H1*z1;

Cheers

Maybe you want

bsxfun(@times,H1,z1)

I guess z1 is a vector

Hello and Thanks for your response

I tried your answer like:

y=bsxfun(@times,H1,z1);

Error using bsxfun

Non-singleton dimensions of the two input arrays must match each other.

Error in Dtrump (line 19)

bsxfun(@times,H1,z1)
