Minimisation of a scaler function

Can someone help me understand this part of the code?

What exactly is the function here?

function [score] = mS(scale, sc, nP, fsl, fp)

'''

score = 0

pS = ST(fSL .* (exp(scale .* SC)))

score = score + pS

return

iS = 5

[bs, bs1] = fminbnd(@(scale) mS(scale, sc, nP, fsl, fp), 0.25 * iS, 5.0 * iS);

'''

The function is ST(fSL .* (exp(scale .* SC))) with varying values of "scale". You did not happen to show the definition of ST

sc, nP, fsl, fp are being passed in as constants

@Walter Roberson Is this similar to a lambda function in python?

[Abhinav Agrawal]

@Walter Roberson Does the value that scale take would be arbitrary or between the range :0.25 * iS, 5.0 * iS?

[Walter Roberson]

yes, similar to lambda, and yes, restricted range
