write

write in a formatted file

Syntax

write(file-desc,a,[format])
write(file-desc,a,k,format)

Arguments

file-desc

character string specifying the file name or integer value specifying logical unit (see file).

This function can not open a UTF filename. In this case, please uses mopen.

a

real matrix or column vector of character strings.

format

character string, specifies a "Fortran" format. This character string must begin with a right parenthesis and end with a left parenthesis. Formats cannot mix floating point , integer or character edition modes

k

integer vector

Description

writes row-by-row a real matrix or a column vector of character strings in a formatted file. Each row of the a argument begin in a new line of file-desc file. Depending on format a given row of the a argument may be written in more than one line of file-desc file.

Format examples : (1x,e10.3,5x,3(f3.0)) , (10x,a20) ;

See a Fortran book for more precision.

Direct access files : x=write(file_desc,a,k,format). Here k is the vector of records (one record by row, i.e. m=prod(size(k))

write(%io(2),....) writes on Scilab's window. Note that in this case format should produce one output line per matrix row. If this constraint is not verified unpredictable behavior could happen.

Examples

if getos() == 'Windows' then unix('del asave');
else unix('rm -f asave'); end
A=rand(5,3); write('asave',A); A=read('asave',5,3);
write(%io(2),A,'('' | '',3(f10.3,'' | ''))')
write(%io(2),string(1:10))
write(%io(2),strcat(string(1:10),','))
write(%io(2),1:10,'(10(i2,3x))')

if getos() == 'Windows' then unix('del foo');
else unix('rm -f foo'); end
write('foo',A)
