Hello,
I was writing this equation in matlab:
y=(3sin(x)cos(x))/(sin3(x)+cos3(x)) % of course 3 means power)
so i wrote it normally like:
y= (3*sin(x)*cos(x))/((sin(x)^3)+(cos(x))^3)
and i got the error: error using m times..Inner matrix dimensions must agree.
although i changed the way of writing it like adding dot and changing parentheses. Where x=0:pi/100:pi/2
I hope you can help me with this.
Thank you.

x = 0:.01:5;
y = (3*sin(x).*cos(x))./((sin(x).^3)+(cos(x)).^3);
