How to write a function?

Please anyone can help me write this following function in matlab

The syntax for declaring a function in MATLAB is: function [y1,...,yN] = myfun(x1,...,xM)

In your case, the function defintion would be:

function v = func_name(m, g, k, t, r)
    v = ((m*g)/k)^0.5 * (1 - exp(-t/r))./(1+exp(-t/r));
end

Thank you sir. I have another question. m,g,k and r are constant, how to plot v function with respect to t

[madhan ravi]

v = ((m*g)/k)^0.5 * (1 - exp(-t/r)) ./ (1+exp(-t/r));
                                   %^ 
plot(t, v)

@Den Jaka as mentioned in the above comment, you can use the plot function to plot function v against t.

Syntax: plot(X,Y)
