Error message

[Mazen Mikha]

Octave is running on Ubuntu 22.04.

This error message is generated when trying to plot,

eml_allow_mx_inputs

here is an example of the script

x = -10:0.1:10;
plot (x, sin (x));
xlabel ("x");
ylabel ("sin (x)");
title ("Simple 2-D Plot");

Any help would be appreciated
