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. ...
collect(P,expr) collects coefficients in P of the powers of the symbolic expression expr. If P is avectoror matrix, then collect acts element-wise on P. If expr is a vector, then collect finds coefficients in terms of all expressions in expr. 使用collect函数,可以针对表达式P中的变量expr进...
Quite simple code 테마복사 syms a b assume(a,'real'); assume(b,'real'); simplify((-1)^a*(b-1)^a) The answer is obviously (1-b)^a, but Matlab does not simplify it? Why? How to make it work? Thank you!댓글 수: 0 댓글을 달려면 로그...

Symbolic Expression Involving Heaviside (symbolic_expression):A symbolic expression involving the Heaviside function is defined as t⋅H(t-2)). Simplify the Expression (simplified_expression):The simplify function is used to simplify the symbolic Expression. ...
The factor function factorizes an expression and the simplify function simplifies an expression. The following example demonstrates the concept −ExampleCreate a script file and type the following code −syms x syms y factor(x^3 - y^3) factor([x^2-y^2,x^3+y^3]) simplify((x^4-16)...
SIMPLIFY(S) simplifies each element of the symbolic matrix S. Examples: simplify(sin(x)^2 + cos(x)^2) returns 1 . simplify(exp(c*log(sqrt(alpha+beta))) returns alpha+beta)^(1/2*c) 4.简化 SIMPLE Search for simplest form of a symbolic expression or matrix. SIMPLE(S) tries several...

Simplify repeating a calculation. For instance, instead of having to type the formulaRparallel = (R1∗R2)/(R1+R2)every time you need it, just create a program calledRparallel.m. • Hide complexity. A user can call a program calledplotFigure2(), for instance, without having to remember...
