PLOT.MATN: plot a matrix of several seismograms

Description

Matrix of several seismograms

Usage

Examples

dt = 0.001

 t = seq(0, 6, by=0.001)

thefreqs = seq(from=10, to=100, by=10)
theamps =  runif(length(thefreqs))

#   % sample rate = 1000 Hz, 0.001 seconds 601 samples
 x = NULL

for(i in 1:length(thefreqs))
{
x = cbind(x, theamps[i]*sin(2*pi*thefreqs[i]*t))
