Operators and Elementary Operations

Perform arithmetic, relational, and logical operations on symbolic objects

Symbolic Math Toolbox™ includes functions for arithmetic, relational, and logical operations, as well as modulo and complex number operations, on symbolic objects. You can use these functions to perform simple operations like addition, multiplication, and calculating exponents, as well as other operations like finding then根，模量并找到了分区的商和其余部分。

Functions

expand all

minus Symbolic subtraction
plus Symbolic addition
times Symbolic array multiplication
ldivide Symbolic array left division
rdivide Symbolic array right division
power 符号阵列功率
nthroot Nth root of symbolic numbers
mtimes Symbolic matrix multiplication
mldivide Symbolic matrix left division
mrdivide Symbolic matrix right division
mpower Symbolic matrix power
转置 Symbolic matrix transpose
ctranspose Symbolic matrix complex conjugate transpose

Operators

eq Define symbolic equation
ge Define greater than or equal to condition
gt Define greater than relation
le Define less than or equal to condition
lt Define less than relation
ne Define inequality

Functions

has Check if expression contains particular subexpression
hasSymType Determine whether symbolic object contains specific type
in Numeric type of symbolic input
isequal Test equality of symbolic inputs
