Read G Code text file with MATLAB

Hello I need to read g code text file with MATLAB

my text file gkod.txt is

; Generated with:
; "Raster 2 Laser Gcode generator"
; by 305 Engineering
;
;
;
G28; home all axes
G21; Set units to millimeters
G90; Use absolute coordinates
G92; Coordinate Offset
G00 X145.0 Y73.0
M03
G01 X137.0 Y73.0 F200
M05
G00 X68.0 Y74.0
M03
G01 X75.0 Y74.0 F200

And I can read all text file with this codes

fid = fopen('gkod.txt','r');
Data=fread(fid);
CharData=char(Data);
fclose(fid);
x=(CharData);
y=transpose(x);
z=(y)

Now I just want to get data containing G0,G1 and if txt have any G2 and G3

Thanks

What output would you like from the above file? What output would you like if the file contained G2 or G3 lines?
