loglog(Y)// It should plot the columns of Y versus their index if Y includes real numbers. If Y includes complex numbers, loglog(Y)and loglog(real(Y),imag(Y)) are equivalent.
loglog(X1,Y1,...)// It plots all Yn versus Xn pairs.
loglog(X1,Y1,LineSpec,...)// It plots all the lines described by the Xn,Yn,LineSpec triples, where LineSpec determine line type, marker symbol,and color of the plotted lines.
loglog(...,'PropertyName',PropertyValue,...)// It sets line property values forall the charting lines created.
loglog(ax,...)// It generates the line in the axes specified by ax instead of in the current axes (gca). The option ax precedes any of the input argument combinations in the previous syntaxes.
h = loglog(...)// It returns a column vector of chart line objects.
