)

Upsample each column of matrix m to achieve f_ups frequency using linear interpolation.

Author
Adam Piatyszek

This function performs upsampling of matrix m to achieve nrof_samples samples at f_ups frequency starting from the sample at t_start time. The frequency of input samples stored in the matrix m is defined by the f_base parameter.
