since i am new to matlab plese help me out with this assignment

find the equation of tangent to the curve y=2(x^1/2) at (1,2)

Supposing M is the 12x12 matrix, then

M([1,2,4],:)=[];
M(:,[1,2,4])=[];

should remove the appropriate rows and columns.

Answer = reshape(r(1:2:end)+r(2:2:end),[],size(r,2))
