Independent Component Analysis ICA

Hi everyone, I need help with ICA

I noticed that there are some methods such as RICA, jadeR function. I am not sure which one is the best method to apply ICA after feature extraction. I tried using jadeR

NumberIC = 3; % number of Independant components we are interested in

FeatureICA = FeatureSignal'; % Cumputing the ICA using the jadeR function

W = jader(FeatureICA,NumberIC);

ICAFinal = (W*FeatureICA)';

These are code i found online, but the third line W = jader(FeatureICA,NumberIC); giving Undefined function 'jadeR' for input arguments of type 'double'. error. Please help me. I dont undersand ICA.
