Simplify expressions involving exponents and logarithms. In the third expression, use log(sym(3)) instead of log(3).If you use log(3), then MATLAB ® calculates log(3) with the double precision, and then converts the result to a symbolic number.

Apr 30, 2014 · Simplifying numbers in symbolic function. Upon substituting into a symbolic expression I get very long analytic expressions for numbers, e.g. (2^ (1/2)* (3^ (1/2)*pi* (5^ (1/2)/4 - 1/4)* (1/120000 + i/6000000)t + .... is there any way to simplify these numbers down to a single double precision complex number in the symbolic expression to make ...

MATLAB constructs the double data type according to IEEE ® Standard 754 for double precision. The range for a negative number of type double is between -1.79769 x 10 308 and -2.22507 x 10-308, and the range for positive numbers is between 2.22507 x 10-308 and 1.79769 x 10 308. For more information on double- and single-precision floating-point values, see Floating-Point …

By default, simplify uses one internal simplification step. You can get different, often shorter, simplification results by increasing the number of simplification steps: S10 = simplify (expr, 'Steps' ,10) S10 =. 2 i e 2 x i + 1 - i. S30 = simplify (expr, 'Steps' ,30) S30 =. cos ( x) - sin ( x) i i cos ( x) - i.
