Description

Use to write one or more vectors to a file. Command will accept any number of vector arguments, including arrays.

The following list shows the different cast types. Note that data can be lost when casting. 'Signed' means the value can be negative. 'Unsigned' means value is always positive.

Cast	Description
`"c"`	Writes each vector channel value as a signed character, or a signed 8 bit (1 byte) value"
`uc"`	Writes each vector channel value as an unsigned character, or an unsigned 8 bit (1 byte) value
`"s"`	Writes each vector channel value as a signed short integer, or a signed 16 bit (2 bytes) value
`"us"`	Writes each vector channel value as an unsigned short integer, or an unsigned 16 bit (2 bytes) value
`"i"`	Writes each vector channel value as a signed integer, or a signed 32 bit (4 bytes) value
`"ui"`	Writes each vector channel value as an unsigned integer, or an unsigned 32 bit (4 bytes) value
`"f"`	Writes each vector channel value as a floating point value, a 32 bit (4 byte) value

Command syntax

Syntax

writeVec "fileID" vecValue1 vecValue2...[-delim string] [-cast string]

Arguments

Name	Type	Comments
`fileID`	int	ID of file previously opened with fileOpen
`vector1`	vector or vector array	One or more values to be written to the file
`vector2`	optional vector or vector array	Command can accept any number of vectors/arrays to write to the file

Flags

Name	Flag arguments	Argument type	Exclusive to	Comments
`delim`	1	string	—	Delimiter to use between vector channel values. Cannot be used with binary files. Usually "," or "\t", etc.
`cast`	1	string	—	Data type to cast to. Possible types are listed above. Note that data can be lost when casting.

Return value

void

Examples

vector $vec = << 100.0, 500.7, -50.5 >>;
int $fileID;
// Open the file and get the ID 
// ...
// Write the vector
// The -delims flag assumes you are writing to a text file 
writeVec $fileID $vec -delims ",";
