plot - 2-D line plot
This MA TLAB function creates a 2-D line plot of the data in Y versus the
corresponding values in X.If X and Y are both vectors, then they must have equal length and MATLAB plots Y versus X.If X and Y are both matrices, then they must have equal size and MA TLAB plots columns of Y versus columns of X.If one of X or Y is a vector and the other is a matrix, then the matrix must have dimensions
such that one of its dimensions equals the vector length.
