Hi Mohammad,
As per my understanding, it appears that you want to obtain the confusion matrix as a matrix variable within your MATLAB workspace.
This can be accomplished using the "confusionmat" function, that takes in known and predicted groups as input and returns the confusion matrix.
Please refer to the following documentation for more information:

This answer shows how to get the confusion matrix as a variable in the MATLAB workspace in 23a, and how to regenerate the confusionchart: https://www.mathworks.com/matlabcentral/answers/2106201-change-class-labels-of-a-confusion-matrix-that-has-been-exported-from-classification-learner
