Dear All,
I have some hyperspectral data was produced by company Itres. Some temperature data is calculated from the average of all the spectral bands hence they do not have wavelength info and I cannot read them with
hypercube
function. Could someone suggest me a solution to read these data?

If you know the height, width, and number of spectral bands of your data, you can try using multibandread(_).
However, in order to use multibandread(_) apart from height, width, bands, you'll also need precision, header offset, interleave value and byte order of your data.
% Specify the parameters
precision = 'double';
headerOffset = 0;
interleave = 'bsq';
byteOrder = 'ieee-le';
height = 100;
width = 100;
bands = 256;
% Read the data
dataCube = multibandread('yourFile.dat', [height, width, bands], precision, headerOffset, interleave, byteOrder);
