MATLAB: I’ m unable to run cpp code in Matlab using mex command. I’m getting following errors.

mex commnand

Error combatgun2.c: 2280 undeclared identifier `new' Error combatgun2.c: 2280 operands of = have illegal types `pointer to COMBATSTATE' and `int' Warning combatgun2.c: 2280 possible usage of new before definition Error combatgun2.c: 2280 syntax error; found `COMBATSTATE' expecting `;'

What should I do? I tried alot. Thanks in advance.

I think you should name your file with the .cpp extension if you have C++ code in it, so the compiler knows to treat it like one. The error about "undeclared identifier `new' " seems to suggest that it is currently compiling as C code. Also make sure that you have selected a compiler that can handle C++ with "mex -setup" (for example, the LCC compiler that ships with MATLAB on 32-bit Windows installation is a C-only compiler).

Hi,

the linker misses "mexFunction", i.e., the entry point. Did you spell "mexFunction" and it's arguments correctly? Take a look at the examples given in the doc and try to compile them (and compare your mexFunction entry with the one given in those).

MATLAB: Plotting Velocity p m m m

This is a boundary value problem. You need to have the initial and boundary conditions to develop the velocity field required for this.

Otherwise, you need to have the velocity field itself to calculate the velocity potential and draw streamlines.

Once you have the velocity field, you can draw the streamlines.

doc streamline

and the velocity potential could be drawn as filled contour below the streamlines.
