How to draw a surface starting from a 3 column vector X, Y, Z with no regular grid on X, Y ?

Dear matlab users,

I have a file out from a fiit element software (ANSYS) which simulats the static distorsion of a metallic plate due to its own weight.

the file gives 3 columns, X, Y, Z

The coordinates X and Y scan the plate surface according to the mesh generated by the ANSYS software. There is no specific structure which would allow to use meshgrid function or so. X and Y are set arbitrarilly.

How is it possible to plot the surface Z associated to the coordinates X,Y?

How is it possible to get an interpolation of such a surface on a regular grid so I can make some analysis with standard tools?

Many thanks for your comments

Cheers

Frederic

Hum, it seems F = scatteredInterpolant(Y,Z,dX) makes the job...

Sorry for the trouble

Another useful function is griddata
