[r,m,b]= regression(i,j);
It is not being possible to find the slope of each row using this command

You could use that function (or many other funs) to get your slope,but u probably could not get all the slopes at one instance. use a loop to help yourself(you also need to provide a corrisponding vector with respect to each row in ur matrix A):
A,t
[dim1, dim2]=size(A);
slope=[];
for i=1:dim1
[s1 slope_tmp s2]=regression(t,A(i,:));
slope=[slope slope_tmp];
end
slope
