Hi, I use GAUSS 17. I am having some trouble to plot and equation (possibility production frontier). I get the error : "G0036: Matrices are not comfortable". I don't get why.
x = seqa(0.1,0.001,3000);
xsq = x^2;
xsqr = sqrt(xsq+48);
z = (x*xsqr);I am trying to plot:
y=((1/32)^(1/3))*(24-(x^2)-(x*sqrt(x^2+48)))*((24+(x^2)+(x*sqrt(x^2+48))))^(-1/3)So sorry for the noob question
Thanks,
Marcos

The last line of your initial code chunk
z = (x*xsqr);will give you the matrices not conformable error, because x and xsqr are both 3000x1 vectors and the * operator performs matrix multiplication in the case in which both of the operands are matrices or vectors. If you use .* i.e. dot multiply, it will perform element-by-element multiplication, like this
z = x .* xsqr;
