Reading and extracting values from a hdr satellite image

I have 20 satellite images with .hdr format. I need to import them in Matlab and extract soil moisture values for certain pixels from them. I used hdrread function but it gives the radiance error. I could open the images with Envi software so I think they are envi hdr types. I found a function called enviread/envihdrread in 'File exchange' but they also dont work. I used notepad to open the header of the file and the information is as follow:

ENVIdescription = {image }

samples = 726

lines = 656

bands = 1

header offset = 0

file type = ENVI Standard

data type = 2

interleave = bsq

sensor type = Unknown

byte order = 1

data ignore value = 0.0

map info = {Geographic Lat/Lon, 1, 1, 14.9012000, 42.5260000, 0.0052, 0.0052, WGS-84}

coordinate system string = {GEOGCS["GCS_WGS_1984",DATUM["D_WGS_1984",SPHEROID["WGS_1984",6378137,298.257223563]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]]}

wavelength units = Unknown

band names = {image }

But I cannot see the 656 lines of information from this image in Notepad. I need to import all these files and read the soil moisture for each pixel in them. Can I get some advice on how to open these images and extract soil moisture values from them? I attach some of the images. Thanks.
