how to treat dataset as matrix

How to treat dataset as a matrix, then I can do sum, diff, time, as the matrix, all the data in the dataset are numerical data.

[Ahmed A. Selman]

The dataset comes from a file or some input device.. or user input function? Each of these (and others) has it's own method to convert data to matrix.

But the cells should be of the same type. if they are different this gives error... how to do this for different types of data in the cells?

If you are talking about converting a dataset array then this might be a possible solution.

First convert your dataset array to cell array using:

C = dataset2cell(D)

and then convert that cell array to simple matrix using:

A= cell2mat(C)

Hope this helps.
