SUMMARY
The forum discussion addresses a common error encountered while plotting graphs in MATLAB. The user initially attempted to calculate the current I using the expression I=(V^3)-(1.4*V)+0.9, which resulted in the error "matrix must be square." The solution provided involves using element-wise operations by replacing the matrix power operator with the element-wise operator, resulting in the corrected code: I=(V.^3)-(1.4*V)+0.9. This adjustment allows for successful plotting of the graph.
