Hi Khatab,
The error you are facing is because of the invalid datatype of “ma” variable in your code. The “pca” function takes input as a matrix of single or double datatype. For more information on the input type, you can check the following documentation - https://www.mathworks.com/help/stats/pca.html#:~:text=the%20trained%20model.-,Input%20Arguments,-collapse%20all
