Stands for the pure imaginary constant, defined asįor Octave to recognize a value as the imaginary part of a complexĬonstant, a space must not appear between the number and the `i'. To specify complex constants, you can write an expression of the formĪll of which are equivalent. Here are some examples of real-valued numericĬonstants, which all have the same value: Values are represented within Octave in double-precision floating pointįormat (complex constants are stored as pairs of double-precisionįloating point values). (exponential) notation, or a complex number.
That can be an integer, a decimal fraction, a number in scientific The simplest form of a numeric constant, a scalar, is a single number There are two types of constants: numeric constants andĪ numeric constant may be a scalar, a vector, or a matrix, and it The simplest type of expression is the constant, which always has Operator Precedence Constant Expressions.Variables, array references, constants, and function calls, as well asĬombinations of these with various operators. As in other languages, expressions in Octave include Statements contain one or more expressions which specify data to be Variable, pass to a function, or assign a new value to a variable withĪn expression can serve as a statement on its own. AnĮxpression evaluates to a value, which you can print, test, store in a Go to the first, previous, next, last section, table of contents.Įxpressions are the basic building block of statements in Octave.
