How to get numerical output

1 view (last 30 days)
Hello, I have been facing some problems with integration, matlab is not giving me numerical output but an output of the form given below. I have also attached part of the code responsible for the output (the loop is just a part of a larger script am using, so the Monthly_parameters(2,n) is caled from elsewhere in he code, which has no problem). How can I resolve this problem to get numerical output. Please can someone assist. What am I not doing well,
for n=1:c
syms x
expr=(Monthly_parameters(1,n)/Monthly_parameters(2,n))*((x/Monthly_parameters(2,n))^(Monthly_parameters(1,n)-1))*exp(-(x/Monthly_parameters(2,n))^Monthly_parameters(1,n))*density*x^3
Power_density_monthly(n,:) = int(expr,[0 25]);
if n==c
display(Power_density_monthly)
Max_power_monthly=0.5*density.*(Wind_speed_MaxE.^3)
Max_Power_annual=0.5*density.*(Wind_speed_MaxE_annual.^3)
Mp_power_monthly=0.5*density.*(Most_probable_wind_speed.^3)
syms x
expr=(Overal_parameters(1)/Overal_parameters(2))*((x/Overal_parameters(2))^(Overal_parameters(1)-1))*exp(-(x/Overal_parameters(2))^Overal_parameters(1))*density*x^3
Mp_power_Overall=int(expr,[0 25])
end
end
Power_density_monthly =
