Hey guys,
I have two matrices: < 57x600x27 double > and < 57x600x14 single >.
1- I got these matrices exactly from identical dataset. What is the reason that one is double and another is single?
2- How can I change the Single to Double? (because I cannot filter it (Chebyshev filter) when it is single and an error message appreas like "_Input arguments must be 'double'").
Thanks for your help!

1- That would depend on how your dataset was generated. We really have no way of knowing that.
2- Use the DOUBLE function. For example, create a matrix of ones of type single, then convert it to a matrix of ones of type double:
double(ones(3,'single'))
