Too many output arguments.

Hi, I am new to matlab and I need help.

Im tring to scale my x vectors by 2 and y vectors by 4.

both x vector and y vecotr has dimension of 1x1000.

the code is below

[c,d]= [2 0;0 4]*[x;y];

when I run the code, I get an error of too many outputs.

Thank you in advance

Why not just

c = 2*x;
d = 4*y;

My professor told me to use the matrix multiplication to solve the problem so I don't think I can.

You cannot do that in MATLAB. The mtimes operator (the formal name for the * operator) only creates a single output argument. You will have to assign the output to a single variable and break apart that single variable into the part representing the new x and the part representing the new y.
