Extracting wavelength vector from an .hdr file

Hi all,
I am fairly new to MATLAB.
I'd like to extract a number of wavelengths as a vector from an .hdr file (see below). They are one value per line, preceded by four spaces, followed by a comma, and start at line 21 and stop at line 224 of the file.
How can I read them into matlab?
Thank you in advance!
.hdr file contents:
ENVI
description = {Data recorded with Specim IQ}
samples = 512
lines = 512
bands = 204
header offset = 0
file type = ENVI
data type = 12
interleave = BIL
sensor type = SPECIM IQ
byte order = 0
default bands = {70,53,19}
latitude = 0.00000000
longitude = 0.00000000
acquisition date = 23-05-2019
errors = none
binning = {1,1}
tint = 3
fps = 150
wavelength = {

Try to use "impot data" option in matlab. Usualy you can define the delimiters, start and end row.
