- Description
- Plot Frequency Response Function with
- Correct label sizes
- Optimized for MIMO systems
- Enable use of custom colors (lightgrey, darkgrey, pink, etc.)
- Adjustable linewidth and marker size
- Easy to adjust limits
- Plot only magnitude or phase using the frfmag() and frfphase() functions
Usage: frf(sys1,'color/linetype/linewidth/marker/markersize',sys2,'color/linetype/linewidth/marker/markersize',...
...{fmin,fmax,magmin,magmax,phasemin,phasemax,wraponoff,type})
Inputs: You can use custom colors, e.g. lightgrey, pink, etc. (see line ~315)
To use the . marker give \. as marker (to distinguist from dots in linewidth specs)
example strings: 'lightgrey--1.5o12' lightgrey dashed line with circle marker of size 12
'orange\.' orange solid line, dot marker
'b*10' blue markers size 10, no line
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.
- Example frf.m vs bode.m
The size of these example pictures is such that they would fit in a two column formatted page, as in journal and conference papers.
