surf2stl.m

在 MATLAB Online 中打开

EDIT: surf2stl is from the File Exchange. Attached here so code can be run

I am trying to convert the surface in to stl format... i am using surf2stl command but i cannot figure how to convert !! any help is appreciated :)

Your calling syntax is incorrect. The function only has 4 inputs, but you are calling it with 7. Please see the syntax guidelines for the function here.

Valid syntaxes are:

SURF2STL('filename',X,Y,Z) writes a stereolithography (STL) file for a surface with geometry defined by three matrix arguments, X, Y and Z. X, Y and Z must be two-dimensional arrays with the same size.
SURF2STL('filename',x,y,Z), uses two vector arguments replacing the first two matrix arguments, which must have length(x) = n and length(y) = m where [m,n] = size(Z). Note that x corresponds to the columns of Z and y corresponds to the rows.
SURF2STL('filename',dx,dy,Z) uses scalar values of dx and dy to specify the x and y spacing between grid points.

yes cris but even when i call 4 functions i am get the same error warning... trying to fix it. thankyou for replying....

What is that error/warning? When I run your code just changing the function call, I get no errors or warnings.

surf2stl('Surface1.stl',xm1,ym1,zm1);
