Matrix Notation Shorthand (MATRIX-END MATRIX command)
You can simplify the construction of matrices using notation shorthand.
Consecutive Integers. Use a colon to indicate a range of consecutive integers. For example,
the vector {1,2,3,4,5,6}
can
be written as {1:6}
.
Incremented Ranges
of Integers. Use a second colon followed by an integer
to indicate the increment. The matrix {1,3,5,7;2,5,8,11}
can be written as {1:7:2;2:11:3}
, where 1:7:2
indicates the
integers from 1 to 7 incrementing by 2, and 2:11:3
indicates the integers from 2 to 11 incrementing
by 3.
- You must use integers when specifying a range in either of these ways. Numbers with fractional parts are truncated to integers.
- If an arithmetic expression is used, it should be enclosed in parentheses.
