If I trained a model using python. Is there any way to import or use that model in matlab? Finally I want to genarate a c code after adding something to that in matlab.

First of all Thank you so much for quick responce.
I have a model in ".SAV" formate right now. I want to import that into matlab and genarate C code for that.
Please let me know if there is any way to do that.
Could you please tell me do you mean MATLAB Coder Toolbox?
If you have any referance links or documents regarding this process please suggest me. Those will help me a lot.
could you please let me know what are all formates of ML models that are developed and trained using python,
Can be accepted by matlab to import ?

I have a doubt here.
if we are converting matlab code from .m to .c, If we have any function which is calling a python method from a .py file then, Is our tool box going to convert the packages that are being called by the python function in .py file?
please let me know if the question is not clear.
I will try to reconstruct or try to send a picture on my question.

To import from Python to MATLAB, save the model in a format MATLAB can import:

or a simpler format, like text or csv.
To generate C code from the imported model, use MATLAB Coder or GPU Coder:

Hi Shayne,
Here is an example that shows how to call GoogLeNet into Simulink using the MATLAB function block:
Deep Learning in Simulink by Using MATLAB Function Block
Also, there are the following blocks that support calling popular model types directly:
Stateful Predict
Stateful Classify
Image Classify
Predict

Hi David,
Thanks for your advise.
I tried this, but I was able to directly get a .h5 file of model weights from keras.
So importkeraslayers(model file) worked well.
But unfortunately the gensim(net) function does not operate on the 'net' file generated from the importkeraslayers function. It shows an error of incorrect argument datatype or missing argument in call to function 'gensim'
Can you provide me with some insight on this. Thanks a ton.
Shayne
