printfmt

Purpose

Prints character, numeric, or mixed matrix using a default format controlled by the functions formatcv and formatnv.

Format

retcode = printfmt(x, mask)
Parameters:
  • x (NxK matrix) – matrix which is to be printed
  • mask (scalar) –

    1 if x is numeric or 0 if x is character.

    • or -

    1xK vector of 1’s and 0’s.

    The corresponding column of x will be printed as numeric where \(mask = 1\) and as character where \(mask = 0\).

Returns:

retcode (scalar) – 1 if the function is successful and 0 if it fails.

Examples

c1 = { "age", "height", "weight" };
c2 = { 31, 70, 160 };

// Horizontally concatenate c1 and c2
c = c1~c2;

// Print 'c' as numeric data
print c;

// Print 'c' as character data
print $c;

// Print column 1 of 'c' as character data and column 2 as
// numeric data
// Note: call disregards the return value
mask = { 0 1 };
call printfmt(c, mask);

The output from the three different print statements will be:

+DEN        31.000000
+DEN        70.000000
+DEN        160.00000
age
height
weight
age               31
height            70
weight           160

Only the final print statement from printfmt() correctly prints both columns.

Remarks

Default format for numeric data is: "*.*lg" 16 8

Default format for character data is: "*.*s" 8 8
