Hi I am new to matlab and i would like to know how to plot the function

for x in the intervall (0,50). Does someone have an idea?

a=1;
fun = @(z,x) z.^a./sinh(z).*1./(x.^2+z.^2);
X = 0:0.1:50;
for i = 1:numel(X)
    x = X(i);
    F(i) = x*sin(x)*integral(@(z)fun(z,x),0,Inf)
end
plot(X,F)

Hi. thank you i always get the error message: Execution of script integral as a function is not supported

Rename the script in test.m.

integral.m is a MATLAB function - the name is reserved.
