loglog

loglog(...,'PropertyName',PropertyValue,...)
h = loglog(...)
loglog(Y)
plots the columns of Y
versus their index if Y
contains real numbers. If Y
contains complex numbers, loglog(Y)
and loglog(real(Y),imag(Y))
are equivalent. loglog
ignores the imaginary component in all other uses of this function.
loglog(X1,Y1,...)
plots all Xn
versus Yn
pairs. If only Xn
or Yn
is a matrix, loglog
plots the vector argument versus the rows or columns of the matrix, depending on whether the vector's row or column dimension matches the matrix.
loglog(X1,Y1,LineSpec,...)
plots all lines defined by the Xn,Yn,
LineSpec
triples, where LineSpec
determines line type, marker symbol, and color of the plotted lines. You can mix Xn,Yn,
LineSpec
triples with Xn,Yn
pairs, for example,
loglog(X1,Y1,X2,Y2,LineSpec
,X3,Y3)
loglog(...,'PropertyName
',PropertyValue,...)
sets property values for all Line graphics objects created by loglog
. See the line
reference page for more information.
h = loglog(...)
returns a column vector of handles to Line graphics objects, one handle per Line.
If you do not specify a color when plotting more than one Line, loglog
automatically cycles through the colors and line styles in the order specified by the current Axes.
Create a simple loglog
plot:
x=
logspace(-1
,
2); loglog(x,exp(x))
