Programs of General Interest

beep:

just make a beep to signal attention

gauss fwhm stp min max:

calculate a gaussian, output goes to console (stdout), the formula for a gaussian is: $\sigma={\rm fwhm}/\sqrt{8*log(2)}$, ${\rm gauss}(x)=\frac{exp(-x^2/2 \sigma^2)}{\sqrt{2*\pi}\sigma}$

gauss2d fwhm1 fwhm2 theta stpx minx maxx stpy miny maxy:

calculate a 2 dimensional gaussian, output goes to console (stdout), the formula for a two dimensional gaussian is: $\sigma={\rm fwhm}/\sqrt{8*log(2)}$, ${\rm gauss}(x,y)=\frac{exp(-u_1^2/2 \sigma_1^2)}{\sqrt{2*\pi}\sigma_1}\frac{exp(-u_2^2/2 \sigma_2^2)}{\sqrt{2*\pi}\sigma_2}$ with $u_1=x cos(\theta)-ysin(\theta)$ and $u_2=y cos(\theta)+xsin(\theta)$, $\theta$ is the rotation angle in degree.

lorentz fwhm stp min max:

calculate a lorentzian, output goes to console (stdout)the formula for a Lorentz curve is: ${\rm lorentz}(x)=\frac{1.0}{\pi{\rm fwhm}(1.0+x^2/fwhm^2)}$

plotbook *.ps:

program plotbook to arrange many (single side) ps-images to one booklet (needs: latex, pstops,ghostscript, perl)

script2html calc1.bat calc2.bat ...

This program creates a html file from scripts containing just the text in the scripts.

 input: calc1.bat, calc2.bat ...    scripts (bat files)
                                   (must be located in the current directory)
 output: stdout      ...........   html file created from the scripts
                                   (use ">" to pipe into file)
 example:

 script2html calc.bat notes.txt > report.html

 [creates the html file report.html from files calc.bat and notes.txt]

setvariable varname value *.*:

sets a variable in a file, e.g. setvariable T 20 Co.sipf replaces T=15 by T=20 in file Co.sipf.

substitute oldtext newtext *.*:

replaces every instance of oldtext with newtext in file(s) *.*
