Re: Applying each element of a vector to each row of a matrix

[Judd Storrs]

The bsxfun function does a lot of this. Assume

a = ones(10) ;
v = 1:10 ;

Multiply each column of a by the corresponding element of v:

bsxfun(@times, a, v)

Multiply each row of a by the corresponding element of v:

bsxfun(@times, a, v')

Raise each column of a to the corresponding power of v:

bsxfun(@power, a, v)

Raise each row of a to the corresponding power of v:

bsxfun(@power, a, v')
