double - MathWorks
double is the default numeric data type (class) in MATLAB ®, providing sufficient precision for most computational tasks. Numeric variables are automatically stored as 64-bit (8-byte) double-precision floating-point values.
Floating-Point Numbers - MathWorks
You can convert numeric data, characters or strings, and logical data to double precision by using the double function. For example, convert a signed integer to a double-precision floating-point number.

2012年12月29日 · Arrays and cell arrays are probably the two most commonly used data types in MATLAB. 1D and 2D arrays are matrices just like in mathematics, in linear algebra. But arrays can also be multidimensional (n-dimensional) arrays, also called tensors, MATLAB calls them multidimensional arrays.
MATLAB® represents floating-point numbers in either double-precision or single-precision format. The default is double precision, but you can make any number single precision with a simple conversion function. MATLAB constructs the double-precision (or double) data type according to IEEE® Standard 754 for double precision.
