Load your dataset into MATLAB or create one using arrays. Ensure that you have a matrix where each row represents an observation, and each column represents a feature, and another column represents the class label.
Use the corrcoef function to calculate the correlation matrix for all features
If you want to compute the correlation matrix for each class separately, you can use the splitapply function.
You can use MATLAB's plotting functions to visualize the correlation matrix. For example, you might use imagesc for a heatmap.

One appropriate code for corr table is this one: https://www.mathworks.com/matlabcentral/fileexchange/30151-shaded-correlation-table
That you can adjust w.r.t. your exercise.
