I have a matrix where the units are dN/dlog(dp), and the columns represent sizes, and the rows represent times
I want to get just dN, so I made a copy of the matrix and called it dN, then made a wave that has the dlog(dp) values in it
I want to multiply each column of the matrix by their corresponding dlog(dp) values

so far I have been trying this:

dN[p][0]=dN[p][0]*dlogdp[0]
.
.
.
dN[p][49]=dN[p][49]*dlogdp[49]

but this method does not work, and usually only changes the first value in the matrix column
Is there any way to get this to work?

Is this what you want?

dN *= dlogdp[q]
