{}

Denotes a vector, matrix, string, or string array definition.

Syntax

{expr_1,expr_2,…,expr_n}

Operand

expr_1, expr_2, ..., expr_n
A set of valid scalar, vector, matrix, string, or string array expressions.

Example

Expression Result
{1} 1
{1, 1+1,1+1+1} 1, 2, 3
{a=2}

{{ {0, a+1}, {a-1, 0}}}

{0, 3}, {1, 0}
{{"This", "is ", "a ", "test"}} {"This ","is ", "a ", "test"}

Comments

If there is only one element within the braces, the result is a scalar expression. Multiple elements define a vector.

If there is only one vector within the braces, the result is a vector expression. Multiple vectors of the same dimension define a matrix of m rows by n vectors.

If there is only one string within the braces, the result is a string expression. Multiple strings define a string array.
