S = simplify(expr) performs algebraic simplification of expr. If expr is a symbolic vector or ma...
In matlab's symbolic math toolbox , you can work with symbolic matrices using thesymfunction to create symbolic variables and expressions , Here's a basic example of how to calculate a matrix symbolically; % Define symbolic variablessymsabcd;% Create a symbolic matrixA=[ab;cd];% Defi...
>> syms x; >> simplify((x^4-81)/(x^2-9)) ans = x^2+9 2.6 使用指数和对数函数求解方程 lambertw是matlab的一个函数意思是x*e^x=W; W = lambertw(Z) solves W*exp(W) = Z. W = lambertw(K,Z) is the K-th branch of this multi-valued function. 不是很清楚lambertw这个表示方式。
simplify(gamma(x + 1) - x*gamma(x)) simplify(besselj(2, x) + besselj(0, x)) ans = 0 ans = (2*besselj(1, x))/x You also can simplify symbolic functions by usingsimplify. syms f(x,y) f(x,y) = exp(x)*exp(y) f = simplify(f) ...
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. ...
