Simplify expressions involving exponents and logarithms. In the third expression, uselog(sym(3))instead oflog(3). If you uselog(3), then MATLAB®calculateslog(3)with the double precision, and then converts the result to a symbolic number. ...
MATLAB Online で開く Ran in: I get a big and jumbled up symbolic output and there are many cos and sines but they dont simplify although I can spot many places where they can combine. Below is a small example where just b is simplified as intended but (b+1) is not. ...
First, go to the Home tab, and create a live script by clicking New Live Script. Define the symbolic variable x and declare the expression as a symbolic expression. Get syms x; expr = 1i*(exp(-1i*x) - exp(1i*x))/(exp(-1i*x) + exp(1i*x)); In the Live Editor tab, ...
Simplify a symbolic expression that contains logarithms and powers. By default,simplifydoes not combine powers and logarithms because combining them is not valid for generic complex values. symsxexpr = (log(x^2 + 2*x + 1) - log(x + 1))*sqrt(x^2); S = simplify(expr) ...
多くの場合、Symbolic Math Toolbox™ でシンボリック式を単純化するには、関数simplifyを使用すれば十分です。しかし、大規模で複雑な数式の場合、simplifyを適用する前に関数expandを使用することで、より単純化された結果をより迅速に得ることができます。
