Hi matlab answers,
My question is embarrisingly simple. I can't get simple things to work. For example, follwowing the mathworks tutorial I tried to read
in a file containg a matrix in a comma separated format. However the "readmatrix" function is undefined. I see nothing in the tutorial about loading a
library to get access to I/O functions. What is going on?

MATLAB is selecting SOFTWARE OPENGL rendering.

Undefined function or variable 'readmatrix'.

I see you are using MATLAB R2018b but the function readmatrix is available from 2019a. Update to R2019a or R2019b to access the function.
