Identifying Numeric Classes - MATLAB & Simulink (original) (raw)
Main Content
You can check the data type of a variable x using any of these commands.
| Command | Operation |
|---|---|
| whos x | Display the data type of x. |
| xType = class(x); | Assign the data type of x to a variable. |
| isnumeric(x) | Determine if x is a numeric type. |
| isa(x, 'integer') isa(x, 'uint64') isa(x, 'float') isa(x, 'double') isa(x, 'single') | Determine if x is the specified numeric type. (Examples for any integer, unsigned 64-bit integer, any floating point, double precision, and single precision are shown here). |
| isreal(x) | Determine if x is real or complex. |
| isnan(x) | Determine if x is Not a Number (NaN). |
| isinf(x) | Determine if x is infinite. |
| isfinite(x) | Determine if x is finite. |
