MATLAB: Does PLOT3 crash when the X vector is an array and the Y and Z vectors are N-dimensional

crashdimensionsfigureMATLABmultipleplotr14

When I run the following code in MATLAB 7.0.1 (R14SP1):
x=[1:100];
y=[cos(x);sin(x)];
z=[tan(x);cot(x)];
plot3(x,y,z);
I get the following error:

Best Answer

This bug has been fixed in Release 14 Service Pack 2 (R14SP2). For previous releases, please read below for any possible workarounds:
We have verified that there is a bug in MATLAB 7.0.1 (R14SP1) in the way that PLOT3 handles a single dimensional X with multi-dimensional Y and Z components. This problem has been fixed in MATLAB 7.0.4 (R14SP2). To work around this issue, make the X vector the same size as Y and Z when providing it to PLOT3.
For example, modify
x=[1:100];
y=[cos(x);sin(x)];
z=[tan(x);cot(x)];
plot3(x,y,z);
to be
x=[1:100];
y=[cos(x);sin(x)];
z=[tan(x);cot(x)];
plot3([x;x],y,z);
