2-D line plot

`plot(`

creates
a 2-D line plot of the data in `X`

,`Y`

)`Y`

versus the corresponding
values in `X`

.

If

`X`

and`Y`

are both vectors, then they must have equal length. The`plot`

function plots`Y`

versus`X`

.If

`X`

and`Y`

are both matrices, then they must have equal size. The`plot`

function 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. If the number of matrix rows equals the vector length, then the`plot`

function plots each matrix column versus the vector. If the number of matrix columns equals the vector length, then the function plots each matrix row versus the vector. If the matrix is square, then the function plots each column versus the vector.If one of

`X`

or`Y`

is a scalar and the other is either a scalar or a vector, then the`plot`

function plots discrete points. However, to see the points you must specify a marker symbol, for example,`plot(X,Y,'o')`

.

`plot(`

plots
multiple `X1,Y1`

,...,`Xn,Yn`

)`X`

, `Y`

pairs using the
same axes for all lines.

`plot(`

sets
the line style, marker type, and color for each line. You can mix `X1,Y1,LineSpec1`

,...,`Xn,Yn,LineSpecn`

)`X`

, `Y`

, `LineSpec`

triplets
with `X`

, `Y`

pairs. For example, `plot(X1,Y1,X2,Y2,LineSpec2,X3,Y3)`

.

`plot(`

creates a
2-D line plot of the data in `Y`

)`Y`

versus the index
of each value.

If

`Y`

is a vector, then the*x*-axis scale ranges from 1 to`length(Y)`

.If

`Y`

is a matrix, then the`plot`

function plots the columns of`Y`

versus their row number. The*x*-axis scale ranges from 1 to the number of rows in`Y`

.If

`Y`

is complex, then the`plot`

function plots the imaginary part of`Y`

versus the real part of`Y`

, such that`plot(Y)`

is equivalent to`plot(real(Y),imag(Y))`

.

`plot(___,`

specifies
line properties using one or more `Name,Value`

)`Name,Value`

pair
arguments. For a list of properties, see Chart Line Properties. Use this option with any of
the input argument combinations in the previous syntaxes. `Name,Value`

pair
settings apply to all the lines plotted.

returns
a column vector of chart line objects. Use `h`

= plot(___)`h`

to
modify properties of a specific chart line after it is created. For
a list of properties, see Chart
Line Properties.
