fscanf (MathScript RT Module Function)
Owning Class: support
Requires: MathScript RT Module
Syntax
a = fscanf(fid, format)
a = fscanf(fid, format, size)
[a, b] = fscanf(fid, format)
[a, b] = fscanf(fid, format, size)
Description
Reads text in a file and converts the text to an appropriate data type.
Inputs
| Name | Description |
|---|---|
| fid | Specifies the identifier for the file you want to read. Use the fopen function to open a file and assign it an identifier. fid is an integer. |
| format | Specifies the format in which to read text from the file. format must use the appropriate format specifier syntax. format is a string. |

Outputs
| Name | Description |
|---|---|
| a | Returns the text that LabVIEW reads from the file specified by fid. a is a vector or matrix of doubles or characters. |
| b | Returns the amount of text that LabVIEW reads successfully from the file specified by fid. b is a positive integer. |
Examples
fid = fopen('test.dat', 'r');
[a, b] = fscanf(fid, '%[a-z] %*d %f', 10);
fclose(fid);
