Home Error When Running Code (Octave/Matlab)
 EDIT: Issues resolved by restarting my Matlab GUI. I was testing my code and ran it multiple times. Without any change in the code, one time I ran it I was presented with an array of errors. Here is the error: warning: load_path: ./lib/jsonlab: No such file or directory warning: load_path: ./lib: No such file or directory warning: load_path: ./lib/jsonlab: No such file or directory warning: load_path: ./lib: No such file or directory warning: load_path: ./lib/jsonlab: No such file or directory warning: load_path: ./lib: No such file or directory error: 'linearRegCostFunction' undefined near line 1 column 8  And the function declaration at line 1: function [J, grad] = linearRegCostFunction(X, y, theta, lambda)  And, finally, the command I entered: [J g] = linearRegCostFunction(X, y, theta, 7)  Thanks in advance for any potential help!
