what is the lowercase L in this expression?

run the following code:

syms s Km1 a Km2 h
q=(s/Km1+s^2/Km1^2/a)/(1+2*s/Km1+s^2/Km1^2/a)-s^h/(s^h+Km2^h)
solve(q,Km2)

get:

exp(-(pi*l*2*i)/h)*((s^h*s^2 + Km1^2*a*s^h + 2*Km1*a*s*s^h)/(s^2 + Km1*a*s) - s^h)^(1/h)

I've never seen that "l" before used by MATLAB's symbolic solver. Any idea what it is? Thanks.

There is nothing special about that lowercase 'l' except that in many fonts it is difficult to distinguish from the numeral '1'. Provided you are using a font that allows you to read it properly there should be no other difficulty in its use. Of course for the purpose of asking a question in this forum, you should always avoid its use since the people attempting to answer will often be confused (as in fact happened here.)
