Description

Plot Frequency Response Function with

• Correct label sizes
• Optimized for MIMO systems
• Enable use of custom colors (lightgrey, darkgrey, pink, etc.)
• Easy to adjust limits

   Usage:   frf(sys1,'color/linetype/marker',sys2,'color/linetype/marker',...
            ...{fmin,fmax,magmin,magmax,phasemin,phasemax,wraponoff,type})

   Inputs:  You can use custom colors, e.g. lightgrey, pink, etc. (see line 180)
            example strings: 'b', 'lightgrey--*', 'orange', '-^'
 
            All elements in the options-struct are optional 
            fmin/fmax in Hz
            magmin/magmax in dB
            phasemin/phasemax in degrees
            wraponoff: [ 'on' | 'off' (default) ]
            type: [ 'mag' | 'phase' | 'magphase' (default) ]

   Outputs: Plots the frf in the current figure.
            Note that the xticklabels might overlap the xlabel in the
            figure. In an exported pdf file they will be correct.
