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 the nth root, modulus, and finding the quotient and remainder of a division.

Functions

expand all

minusSymbolic subtraction
plusSymbolic addition
timesSymbolic array multiplication
ldivideSymbolic array left division
rdivideSymbolic array right division
powerSymbolic array power
nthrootNth root of symbolic numbers
mtimesSymbolic matrix multiplication
mldivideSymbolic matrix left division
mrdivideSymbolic matrix right division
mpowerSymbolic matrix power
transposeSymbolic matrix transpose
ctransposeSymbolic matrix complex conjugate transpose

Operators

eqDefine symbolic equation
geDefine greater than or equal to condition
gtDefine greater than relation
leDefine less than or equal to condition
ltDefine less than relation
neDefine inequality

Functions
