Peak Generation
Contents
emgpeak: Generate exponential modified Gaussian peaks
fspeak: Generate a number of Fraser-Suzuki peaks
gspeak: Generate a number of Gaussian peaks
Noise Generation
Contents
clnoise: Generate coloured noise records, given autocorrelation function of desired noise
firnoise: Generate noise records using a known noise shaping filter
fonoise: Generate first order bandlimited white noise
fnoise: Generate noise according to the arctangent model. This is an approximation of 1/f noise (flickernoise)
mnoise: Generate a set signals, that have correlation in time and mutual correlation

addDate: add a date stamp to a plot
defplot: Set default plotting options
ellipse: Draw ellipse
nplot: Normalized plot of set of curves
nsplot: Normalized stacked plot of set of curves
paxis: Normalized stacked plot of set of curves
plotmixtdes: plot a mixture design
