idplot    Examples

Plot input-output data.

Syntax

idplot(z)
idplot(z,int,T,ny,pc)

Description

z is the output-input data z = [y u] to be graphed. A split plot is obtained with the output on top and the inputs, one by one if several, at the bottom. Pressing the Return key advances the plot.

The data points specified in the row vector int are graphed. The default value of int is all the data. You can use the sampling interval T (default T = 1) to give correct time axes.

The argument ny is the number of outputs in the data matrix. Default is
ny = 1. The input is piecewise constant between sampling points, and it is graphed accordingly. If you prefer linear interpolation between input data points, use pc = 'li'. The default value is pc = 'pc'.

Examples

Plot only a portion of the data points:
