Contourc input limited to double (bug?)

In contourc function description Z input can be any of single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64.

But in practice it works only for double, and return error for all others.

Example:

x = -5:0.5:5;

y = -5:0.5:5;

[Xm,Ym] = meshgrid(x,y);

Z = Xm.^2 + Ym.^2;

M = contourc(x,y,single(Z),10);

Hi Sasha,

I understand that you are trying to use the “contourc” function in MATLAB for input arguments of type “single” and facing an error.

This is a known issue and for the workaround please refer to the following article posted by the MathWorks Support Team.

I hope this information helps resolve the issue you are facing.
