fprintf

Arguments

format

a Scilab string. It specifies a character string combining literal characters with conversion specifications.

value_i

specifies the data to be converted according to the format parameter.

file

a Scilab string specifying a file name or a logical unit number (see file)

Note that if file=0, the message will be display on standard error stream (stderr).

Description

This function is obsolete and will be removed in Scilab 5.5.0, use preferabily the mfprintf function which is much more compatible with the C fprintf functionalities.

The fprintf function converts, formats, and writes its value parameters, under control of the format parameter, to the file specified by its file parameter.

The format parameter is a character string that contains two types of objects:

Literal characters

which are copied to the output stream.

Conversion specifications

each of which causes zero or more items to be fetched from the value parameter list. See printf_conversion for details.

If any values remain after the entire format has been processed, they are ignored.

Examples

u=file('open',fullfile(TMPDIR,'results'),'unknown') //open the result file
t=0:0.1:2*%pi;
for tk=t
  fprintf(u,'time = %6.3f value = %6.3f',tk,sin(tk)) // write a line
end
file('close',u) //close the result file

fprintf(0,'My error which is going to be displayed on the stderr')
