How do I make a function work with vectors?

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)))

tanH = (exp(x)-exp(-x))./(exp(x)+exp(-x))
