I want to read data and variables from a specially formatted file as MATLAB variables. Preferably into a structure.
I am looking for the best approach for a quick solution. unfortunately I am stuck. Maybe someone can give me a helpful hint.
Data in the file have the strucktur:
[variable name]
data
[-]
[variable name]
x1 y1
x2 y2
x3 y3
[-]
A shortened example file:
Instrument Name
File Format Version
[DateTime]
1643810991
[-]
[GenParams]
[CableID]
[-]
[FiberID]
[-]
[FiberType]
0
[-]
[Settings]
[Wavelength]
1
[-]
[PulseWidth]
7
[-]
[End]
35.000
[-]
[Start]
0.000
[-]
[DataPoints]
0.011 -5.000
0.011 -5.000
0.036 -5.000
0.061 -5.000

Of course, I've already looked at the manufacturer, who doesn't provide anything. the company is also far too small and the product far too niche. I will have to tackle the task myself.
I haven't built a praser yet. now I'm looking for information how to do that

Ran in:
rgx = '\[(\w+)\]\s*([^\[]+)\[\-\]';
str = fileread('test.txt');
tkn = regexp(str,rgx,'tokens');
tkn = vertcat(tkn{:});
tmp = cellfun(@str2num,tkn(:,2),'uni',0);
out = cell2struct(tmp,tkn(:,1),1);
out.DateTime = datetime(out.DateTime,'ConvertFrom','posix')
out = struct with fields:
DateTime: 02-Feb-2022 14:09:51 CableID: [] FiberID: [] FiberType: 0 Wavelength: 1 PulseWidth: 7 End: 35 Start: 0 DataPoints: [4×2 double]
out.DataPoints
ans = 4×2
0.0110 -5.0000 0.0110 -5.0000 0.0360 -5.0000 0.0610 -5.0000
