I am using writematrix to write a 2D matrix to csv, and read this csv later elsewhere (e.g., Python Numpy).
The problem is that this file always errors, even when I read this file using textread.
Would you please help me?
Here is a sample code to reproduce the issue:
filename_ = 'sample_matrix.csv';
writematrix(rand(20,30), filename_);
textread(filename_) % this errors

The format specification is mandatory for textread

textread must be given at least two parameters. textread is for reading formatted data and you have to tell it the format. textread is not for reading a file as a single character vector: I already gave links to two routines for that.
