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。

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. ...
simplify((x^4-16)/(x^2-4)) 1. 2. 3. 4. 5. 当您运行该文件,它会显示以下结果: ans = (x - y)*(x^2 + x*y + y^2) ans = [ (x - y)*(x + y), (x + y)*(x^2 - x*y + y^2)] ans = x^2 + 4 1.
Expand Symbolic Expression syms x p = (x - 2)*(x - 4); expand(p) ans = x^2 - 6*x + 8 Expand Trigonometric Expression Expand the trigonometric expression cos(x + y). Simplify the cos function input x + y to x or y by applying standard identities. syms x y expand(cos(x + ...
