mprintf
converts, formats, and writes data to the main scilab window
printf
converts, formats, and writes data to the main scilab window (obsolete)
Syntax
mprintf(format,a1,...,an);
Arguments
- format
a string providing the format to use to write all next arguments. The
format
follows -- as close as possible -- the C printf format operand syntax, as described in the printf_conversion page. UTF-8 extended characters and numbered placeholders "%n$.." are supported.- a1,...,an
Data to be converted and printed according to the
format
argument. Supported types: all numbers, booleans, strings. Only the real part of complex numbers is considered (current Scilab limitation).
Description
mprintf(format, a1, a2, ..)
replaces placeholders provided inside the
format
string with values of a1
, a2
, ..
converted according to each respective placeholder directive, and writes the result to
the Scilab console.
If a1
, a2
, .. are arrays with multiple rows,
they feed the format row by row: the format is used iteratively for every row of the
(horizontally "concatenated") arrays, until the bottom
of the least tall array is reached. Remaining rows of taller arrays (if any) are ignored.
See examples.
If the total number of columns of a1
, a2
, ..
is bigger than the number of placeholders in the format
,
then extra columns are ignored. If it is smaller, an error is yielded.
The mprintf
function is an extended interface for C-coded
printf
.
Examples
I = (1:4)'; A = [26.93 ; 63.25 ; 40.51 ; 91.84]; B = [ 3.62 ; 15.04 ; 25.3 ; 48.19]; C = [ 4.37 28.06 48.18 %inf 41.48 %nan 26.39 77.83]; Status = ["NOK" "NOK" "NOK" "OK"]'; Format = "Iteration %d: Results: A= %f B= %2d%% Status= %3s C(1)= %g C(2)= %e\n"; mprintf(Format, I, A, B, Status, C);
--> mprintf(Format, I, A, B, Status, C); Iteration 1: Results: A= 26.930000 B= 3% Status= NOK C(1)= 4.37 C(2)= 2.806000e+01 Iteration 2: Results: A= 63.250000 B= 15% Status= NOK C(1)= 48.18 C(2)= Inf Iteration 3: Results: A= 40.510000 B= 25% Status= NOK C(1)= 41.48 C(2)= Nan Iteration 4: Results: A= 91.840000 B= 48% Status= OK C(1)= 26.39 C(2)= 7.783000e+01
Supernumerary columns or rows are ignored:
A = [%T %F %T %T %F]'; B = [ 4.37 28.06 48.18 %inf 41.48 %nan ]; mprintf("OK? %s Value: %4.1f\n", A, B);
--> mprintf("OK? %s Value: %4.1f\n", A, B); OK? T Value: 4.4 OK? F Value: 48.2 OK? T Value: 41.5
Numbered placeholders "%n$.." allow reordering printed data with the format:
names = ["Peter", "Martha" "John"]'; ages = [32 25 8]'; mprintf("%2$6s is %1$d-year old.\n", ages, names);
--> mprintf("%2$6s is %1$d-year old.\n", ages, names); Peter is 32-year old. Martha is 25-year old. John is 8-year old.
