Calculate derivatives of "a matrix"

Hi at all, I have a polynomials coefficients matrix of W rows in the form f(x)= ax^2 + bx + c

M= [a1 b1 c1 ; a2 b2 c2 ; ... ... ...];

I calculate the derivatives of each polynomial :

M1der=polyder(M(1,:))

for each rows...

Is there a command to calculate the derivatives coefficients matrix?

The important is that the new matrix as 1 value in 1 cell, not all-in-one.

Thanks so much

M1der=[2*M(:,1),M(:,2)];

or more generally for degree n polynomails

 M1der=bsxfun(@times,M(:,1:end-1), n:-1:1);

Thanks, but I mean for all matrix, not for a single row.

Yes. That's what I've given you.
