Format a large number into small decimal number

2 次查看(过去 30 天)
Hello,
I have code on function like:
hr = sqrt ( .1/ 2 ) .* (h_i+j*h_q);
hr1 = sqrt (.3/ 2 ) .* (h_i+j*h_q);
x=x = constellation(randi([1 4],50));
syms cr;
r=(hr*x+hr1*cr);
and I am getting the answer like cr*(2031273339923201/4503599627370496 - 7019058886806809i/36028797018963968) - 42472189963858493/288230376151711744)
How I will format this large number into small decimal number?

Lookup matlab built-in functions like simplify() or vpa().
This should do the work:
vpa(r, 4)
