TypeComponents |
A single name that contains three parts. The first part is one of the scalar types. The second part is the number of rows. The third part is the number of columns. The number of rows and columns is a positive integer between 1 and 4 inclusive. |

An ASCII string that uniquely identifies the variable name. |
Examples
Here are some examples:
int1x1 iMatrix; // integer matrix with 1 row, 1 column
int4x1 iMatrix; // integer matrix with 4 rows, 1 column
int1x4 iMatrix; // integer matrix with 1 row, 4 columns
double3x3 dMatrix; // double matrix with 3 rows, 3 columns
float2x2 fMatrix = { 0.0f, 0.1, // row 1
2.1f, 2.2f // row 2
};
A matrix can be declared using this syntax also:
matrix <Type, Number> VariableName
The matrix type uses the angle brackets to specify the type, the number of rows, and the number of columns. This example creates a floating-point matrix, with two rows and two columns. Any of the scalar data types can be used.
Here is an example:
matrix <float, 2, 2> fMatrix = { 0.0f, 0.1, // row 1
2.1f, 2.2f // row 2
};
