You can use fsolve() for such problems. For example
fun = @(x) exp(-0.005*x).*cos(0.05*(2000-0.01*x.^2).^(0.05))-0.01
sol = fsolve(fun, rand())
Note that, the code you included in your question contain exp(1)^(-0.005*x). That is very inefficient.
If you just want to graph it then try
x = linspace(0,2*pi,100);
y = exp(-0.005*x).*cos(0.05*(2000-0.01*x.^2).^(0.05))-0.01;
plot(x,y)
Note that I have replaced * with .* and ^ with .^. Read about element-wise operators here: https://www.mathworks.com/help/matlab/matlab_prog/array-vs-matrix-operations.html
