# Math Help - I have little problem with 3D plot in Maple

1. ## I have little problem with 3D plot in Maple

Hi peoples,I have little problem with 3D plot in Maple
I am build my function in this way:

mu1(x,y) := (100e6*Transpose(Vector([300,0]))*(Vector([-10,-10])-Vector([x,y])))/(VectorNorm(Vector([-10,-10])-Vector([x,y]),2)*3e8);

mu3(x,y) := (100e6*Transpose(Vector([300,0]))*(Vector([10010,10010])-Vector([x,y])))/(VectorNorm(Vector([10010,10010])-Vector([x,y]),2)*3e8);

mu2(x,y) := (100e6*Transpose(Vector([300,0]))*(Vector([10010,-10])-Vector([x,y])))/(VectorNorm(Vector([10010,-10])-Vector([x,y]),2)*3e8);

costf(x,y) := (2*775.6-870.67-897.06+(mu2(x,y)+mu3(x,y)-2 *mu1(x,y))^2) +(2*870.67-775.6-897.06+(mu1(x,y)+mu3(x,y)-2 *mu2(x,y))^2)+ (2*897.06-775.6-870.67+(mu1(x,y)+mu2(x,y)-2* mu2(x,y))^2);

plot3d(costf(x, y), x = 0 .. 10000, y = 0 .. 10000);

Warning, unable to evaluate the function to numeric values in the region; see the plotting command's help page to ensure the calling sequence is correct.

In addition, How I can send all constants that exist here (besides x and y) from Matlab.
