upper

Purpose

Converts a string, matrix of character data, or string array to uppercase.

Format

y = upper(x)
Parameters:x (string or NxK matrix, or string array) – the character data to be converted to uppercase.
Returns:y (string or NxK matrix or string array) – containing the uppercase equivalent of the data in x.

Examples

// Create a lowercase string
x = "uppercase";

// Convert the string to upper case
y = upper(x);

// Adding the '$' tells GAUSS to treat the data as character
// data
print $y;

This code produces:

UPPERCASE

Remarks

If x is a numeric matrix, y will contain garbage. No error message will be generated since GAUSS does not distinguish between numeric and character data in matrices.
