M(M==min(M))=nan % where M is your matrix

My matrix is 3*10 double

it shows Error using ==

Matrix dimensions must agree.

and plz include this condition in code

condition is if the value in each column is not more than 15% of maximum value of that column

"Replace minimum value of each column with nan"

M(bsxfun(@eq,M,min(M)))=nan
