Helper routine to transform 1d arrays into column vectors that are needed by other routines in Chronux Usage: data=change_row_to_column(data) Inputs: data -- required. If data is a matrix, it is assumed that it is of the form samples x channels/trials and it is returned without change. If it is a vector, it is transformed to a column vector. If it is a struct array of dimension 1, it is again returned as a column vector. If it is a struct array with multiple dimensions, it is returned without change Note that the routine only looks at the first field of a struct array. Ouputs: data (in the form samples x channels/trials)
