Syntax
plot(data) plot(d1,...,dN) plot(d1,PlotStyle1,...,dN,PlotStyleN)
Description
data is the output-input data to be graphed, given as an iddata object. A split plot is obtained with the outputs on top and the inputs at the bottom.
One plot for each I/O channel combination is produced. Pressing the Return key advances the plot.
To plot a specific interval, use plot(data(200:300)). To plot specific input/output channels, use plot(data(:,ky,ku)), consistent with the subreferencing of iddata objects. (See iddata).
If data.intersample = 'zoh', the input is piecewise constant between sampling points, and it is then graphed accordingly.
To plot several iddata sets d1,...,dN, use plot(d1,...,dN). I/O channels with the same experiment name, input name and output name, will always be plotted in the same plot.
With PlotStyle, the color, linestyle and marker of each data set can be specified.
plot(d1,'y:*',d2,'b')
just as in the regular plot command.
