As far as I know, Igor Pro is one of the best analysis software for scientific and engineering researches.
You can analyze your data with very efficient and intuitive way by using only mouth and click.
However, if you could use programing on the Igor Pro, you can reach to much high level analysis while the programing on the Igor Pro is a bit tricky.
Here, I would like to write just a simple way how to make program on the Igor Pro.
The detail of the programing is referred to the manual of the Igor Pro.
First approach to write a programming on the Igor Pro is to make a "function".
"function" is a program having functionality and written in procedure, that can be made by
Windows -> New -> Procedure…
The name of the procedure window is determined as
As a result, you can see the window to write program on the Igor Pro.
When you are new for the programing, you do not have to care about the initial notation of
"#pragma rtGlobals=3// Use modern global access method and strict wave access."
The font for the procedure can be changed by
Procedure -> Text Size ->
The setting for the procedure can be saved by
Procedure -> Capture Procedure Prefs...
Now, you are ready to write a program.
The easiest function would be a function to do nothing, which is given by
Function doNothing()
End
The "Function" indicates this program is a function.
The following string of "doNothing" is the name of function.
You need put "()" after the name of the procedure.
Detail in the inside of "()" would be given somewhere else.
All function must be ended with "End".
You can call this function by writing the name of this function of "doNothing" in the command line as
This gives
Note that this function gives nothing since we wrote nothing in the function.
The second example is the typical program for the all programing language of saying "Hello world".
This is given by
Function sayHelloWorld()
print "Hello world"
end
This function gives
The "print" command give the following string of "Hello world" in the command line as shown above.
I strongly recommend you to include only one functionality in one "function".
Much complicated functions, which has two or more functions, should be realized by combining "function"s.
The third example calls three command of "command 1", "command 2", and "command 3" as
When I call "callAllCommandsOf123", this gives
The great point of the programming on the Igor Pro is that you do not have to remember the command.
For example, the command to plot the data of dataY vs. dataX is achieved by the button of "To Clip" in New graph window of
This gives "Display dataY vs dataX" so we know the command to get a new graph is "Display".
The function to plot a new graph is
When you want to perform Fourier transform of dataX, the command is achieved by the button of "To Clip" in the Fourier Transforms window of
This gives "FFT/OUT=1/DEST=dataX_FFT dataX".
Thus, the function for the FFT is
When the configuration for the analysis must be changed, like you calculate the magnitude for the Fourier transform and the result is plotted in a new graph, you can get the command by the button of "To Clip" in the window of
This gives command of "FFT/OUT=3/DEST=dataX_FFT dataX".
