Get water distribution system data from an EPANET input file

Description

Syntax

[x] = getwdsdata(wdsfile, code)
[x] = getwdsdata(wdsfile, code, id)
[x,t] = getwdsdata(...)

Description

[x] = getwdsdata(wdsfile, code) returns static water distribution system data for all nodes/links from an EPANET 2 input file. The type of data is specified by the epanet 'code'.

[x] = getwdsdata(wdsfile, code, id) returns static water distribution system data for the nodes/links specified in cell array of strings 'id' from an EPANET 2 input file.

[x,t] = getwdsdata(...) returns dynamic water distribution system data with the time steps from an EPANET 2 input file.

Example

[cl, t] = getwdsdata('Net1.inp', 'en_quality', {'2', '12'})

• MATLAB release: MATLAB 6.5 (R13)
• Other requirements: Zip contains epanet2.dll and header file.

A much needed utility for researchers using the EPANET toolkit with Matlab. This probably saved a month of start-up time for me.
More documentation or comment lines would go a long way.

There are some codes that do not work with the program

[Demetrios Eliades]

In some computers the code does not run, due to a missing filename in line 81:
[errorcode] = calllib('epanet2', 'ENopen', wdsfile, '', '')

By changing to
[errorcode] = calllib('epanet2', 'ENopen', wdsfile, 'tmp.$$$', '')
everything works OK.
