iPlot - Interactive Plot

iPlot is a MATLAB tool for plotting 1-D or 2-D matrices interactively. Data is plotted versus row indices.

• iplot(X) plots the columns in X (or their spectral amplitude) interactively, one at a time. X can be a matrix or a vector.
• iplot(X,Y,...) plots the columns in X,Y…, one above the other for easy comparison.

Functionality

iPlot functionalities are triggered by pressing keys (see keyboard legend below). Main functionalities include:

• move forward or backward between the columns of the input matrix [“A” and “D” keys]
• plots the spectral amplitude of the current column [ “F” key ]
• various column ordering (sequential, std +, std -, random) [“R” key]
