Z = complex(a,b) z = a + bi for real a, b int8(5)) and are mainly for compact storage, not for computations.Īll data are considered as matrices, with scalars, row and column vectors as special cases.
Integer data types of different size exist, they have to be specified explicitly (e.g. In this case, the evaluation will switch to complex arithmetic, and data will be allocated as (double) complex automatically. Complex numbers may appear as input of expressions or results of function calls. Numerical data are 64bit (double precision) real floating point numbers by default. Whos -name pat list all variables starting with pat give access to named variablesĬlearglobal a b. On the other hand, function calls with an empty argument list often allow to drop the brackets, e.g. In this way, assignments to variables like beta, gamma will hide the corresponding functions (with a warning). It appears that variables and functions share the same name space. Maximal length is 24 characters (the rest will be ignored).
Special characters % _ # ! $ ? (percent as 1st character only) Its type and size is (re)allocated automatically. If the result is assigned to a variable: var = expression as follows:įormat('v', 10) variable format, up to 10 digits (default)įormat('e', 16) exponential format, up to 16 digits The standard format for numerical output is changed e.g. The result is echoed in a standard numerical format, except for the semicolon, which implies quiet evaluation.
