MATLAB: How to make a function work with vectors

functionhelp

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)))

Hi, check this code out, its the correct code.

%% YOUR CORRECT CODE
x = 0:0.1:2;
y1 = exp(x)./(exp(x)+1);
figure
plot(x,y1,'r--o','LineWidth',2)

MATLAB: Re-sizing vectors

If you want to change the range of the y-values, you can do it by first normalizing and then denormalizing to your required range

x = [1xn signal]
xNormalized = (x-min(x))/(max(x)-min(x))
newMin = 0;
newMax = 90;  % new minimum and maximum value of the signal you want
xNew = xNormalized*(newMax - newMin) + newMin;

xNew will have same shape of x but varies from newMin to newMax.
