Error while generating code using griddedinterpolate in matlab function

Hello all,

I want to generate code of my model which has a matlab function that performs 2D interpolation using griddedIterpolae command.I'm getting thwe below error.I have also attached the snippet of my code inside the matlab function.Could you please help me with this

You can remove the line

volumetric = 0 ;

Any ways this is not the cause for error. What version you are using? Don't attach code as an image snippet. copy paste the code/ error here.

I'm using Matlab 2018b and griddedInterpolant

griddedInterpolant is still not supported for code generation: https://www.mathworks.com/help/referencelist.html?type=function&capability=codegen&listtype=alpha. You will need to rely on some alternate methods.

Thank you Ameer.

Other Atlernate like interp2?

[Ameer Hamza]

interp2 is supported. The complete list is available here: https://www.mathworks.com/help/referencelist.html?type=function&capability=codegen

So, I've noticed that interp2/interp3 is supported. But if you look inside interp3, it seems like it re-packages your data into a griddedInterpolant object and then uses it. Does anyone know why griddedInterpolant itself isn't supported?

I would like to make the griddedInterpolant object as a persistent variable and just call it as new data goes through the function.
