Example of using RADIS from Matlab

All methods of RADIS can be accessed using py.radis followed by the method to be accessed

In the lines below, we emulate Matlab syntax to generate the example on this online documentation, so that lines be copied directly into Matlab.

See the real Matlab file : https://github.com/radis/radis/blob/develop/examples/calc_matlab.m See https://github.com/radis/radis/pull/547 for more details and screenshots of Radis running in Matlab directly

from radis.test.utils import EmulateMatlab  # this line is not needed in Matlab

py = EmulateMatlab()  # this line is not needed in Matlab

All lines below can be copied in Matlab directly :

s = py.radis.calc_spectrum(
    1900,
    2300,
    molecule="CO",
    isotope="1,2,3",
    pressure=1.01325,
    Tgas=700,
    mole_fraction=0.1,
    path_length=1,
    databank="hitran",
)
s.apply_slit(0.5, "nm")

The 'delim_whitespace' keyword in pd.read_csv is deprecated and will be removed in a future version. Use ``sep='\s+'`` instead
