Sometimes MATLAB users need to scale the y-axis as a log scale keeping the x-axis as a linear scale while plotting a function or an expression. This can be obtained easily by using thesemilogy()function. Thesemilogy()function allows us to create two-dimensional plots of a function or expr...

loglog(X,Y) plots x- and y-coordinates using a base-10 logarithmic scale on the x-axis and the y-axis. To plot a set of coordinates connected by line segments, specify X and Y as vectors of the same length. To plot multiple sets of coordinates on the same set of axes, specify at...
