getcomp

float  getcomp(<vector>v, int index)

Returns the vector component at the given index. This is the same as v[index].

float  getcomp(<matrix>m, int row, int column)

Returns the matrix component at the given location.

<type> getcomp(<type>array[], int index)

Returns the array item at the given index. This is the same as array[index].

<type> getcomp(<vector>array[], int i, int j)

Returns the vector component at the given location and array index. This is the same as getcomp(array[i], j).

<type> getcomp(<matrix>array[], int i, int j, int k)

Returns the matrix component at the given location and array index. This is the same as getcomp(array[i], j, k).

<type> getcomp(dict d, string index)

<type>[] getcomp(dict d, string index)

Returns the dictionary item at the given index. This is the same as d[index].

<type> getcomp(dict d, string index, <type>defvalue)

<type>[] getcomp(dict d, string index, <type>defvalue[])

Returns the dictionary item at the given index. If it doesn’t exist, return defvalue. This is the same as isvalidindex(d, index) ? d[index] : defvalue.

string  getcomp(string value, int index)

Returns the character at the given index. This is the same as value[index].

Characters in VEX are strings as well. UTF-8 encoding is used, so if the index is part way through a UTF-8 encoding, the result is an empty string. Otherwise it is the entire valid UTF-8 character.
