Hi,
I have a matrix m and want to set all elements that are NaN, Inf or -Inf to the minimum of the corresponding column. For example: If m(r,c) is non-finite, it should be set to the lowest finite value of column c.
How can this be done (preferably without looping)?
Thanks...

m(~isfinite(m))=nan;
minvals=min(m,[],1);
m=bsxfun(@max,m,minvals);
