dynamically name function output

I would like to to dynamically name fuction output based on some inputs

Like: As my variable para.algo will be changing, is it possible automatically append it to the output SIR?

para.algo='RPIS';
[SIR, ~] = bss_eval_mix(W.', Htheo.');

% I dont want to manually write this, 
% I would like it to be done automatically using value of algo
[SIR_RPIS, ~] = bss_eval_mix(W.', Htheo.');

That approach will force you into writing slow, complex, obfuscated code and makes accessing the data harder. Your code will break for any para.algo that contains characters that are not valid in MATLAB variable names.

Just use simple, efficient indexng to store both the function output and the algorithm name.
