mfscanf Scilab Group Scilab Function mfscanf
NAME
mscanf - interface to the C scanf function mfscanf - interface to the
C fscanf function msscanf - interface to the C sscanf function
CALLING SEQUENCE
[n,v_1,...v_n]=mfscanf(fd,format)
L=mfscanf(fd,format)
[n,v_1,...v_n]=mscanf(format)
L=mscanf(format)
[n,v_1,...v_m]=msscanf(format,str)
L=msscanf(format)
PARAMETERS
format : a Scilab string describing the format to use to write the
remaining operands. The format operand follows, as close as
possible, the C printf format operand syntax.
fd :The fd parameter returned by the function mopen is used as a
file descriptor (it's a positive integer). When specifying the fd
parameter, the value -1 refers to the default file ( i.e the last
opened file).
str : a Scilab string.
n : an integer, the number of data read or -1 if EOL has been
encountered before any datum has been read.
v_i : Each function reads characters, interprets them according to a
format, and stores the results in its output arguments. If
more than $n$ output arguments are provided, the last ones
v_n+1,...v_m are set to empty matrices.
L : a matrix of strings or numbers if data read are homogeous or an
mlist of type (cblock) containing a sequence of homogeneous
matrices
DESCRIPTION
The mfscanf function reads characters from the stream fd.
The mscanf function reads characters from Scilab window.
The msscanf function reads characters from the Scilab string str.
EXAMPLES
s='1 1.3'
[n,a,b]=msscanf(s,"%i %e")
msscanf(s,"%i %e")
msscanf(" 12\n",'%c%c%c%c') //scan characters
msscanf('0xabc','%x') //scan with hexadecimal format
msscanf('012345abczoo','%[0-9abc]%s') //[] notation
//create a file with data
u=mopen(TMPDIR+'/foo','w');
t=0.5;mfprintf(u,"%6.3f %6.3f\n",t,sin(t))
t=0.6;mfprintf(u,"%6.3f %6.3f\n",t,sin(t))
mclose(u);
//read the file
u=mopen(TMPDIR+'/foo','r');
[n,a,b]=mfscanf(u,'%e %e')
l=mfscanf(u,'%e %e')
mclose(u);
