there is hsv to rgb conversion but no formula for hyperspectral image to rgb conversion (hsi2rgb). Can you please provide solution for that too?

Thanks in advance

MATLAB/IPT do not have tools for HSI or HSL. There are multiple submissions on the File Exchange, some of which are only one-way, some of which have bugs. This portion of MIMT includes bidirectional HSI-RGB conversion tools:

If you're trying to create false-color images from hyperspectral data, you can use colorize(). That requires you have IPT and a newer version, and you need to install the Hyperspectral Imaging Library.
