I have this function
function tanH = TAN(x)
tanH(x)=((exp(x))-(exp(-x)))/((exp(x))+(exp(-x)))
end
and I need to change it so that I can get answers if x would be a vector. I've tried putting dots but can't get it to work. What should i be doing?
Thanks in advance.

Use element-wise divide operator ./ (with the dot) instead of the matrix divide operator / (without the dot). E.g.,
tanH(x)=((exp(x))-(exp(-x)))./((exp(x))+(exp(-x)))
