Hi,
You may use the 'Statistics and Machine Learning Toolbox'.
Refer to the following documentation links to get started with classification using Support Vector Machines (SVM).
- SVMs and Kernel definitions : https://www.mathworks.com/discovery/support-vector-machine.html
- Using SVM classifier with Gaussian Kernel : https://www.mathworks.com/help/stats/support-vector-machines-for-binary-classification.html#bss0s6_-1
- Creating SVM template with Gaussian Kernel example :https://www.mathworks.com/help/stats/templatesvm.html#bug4e0t-1
Hope this helps!
