NAME

Math::Giac - A perl interface to giac, a CAS(Computer Algebra System)

VERSION

Version 0.0.1

SYNOPSIS

    use Math::Giac;

    my $giac;
    eval( {
       $giac=$Math::Giac->new;
    } );
    if ( $@ ){
        die("Failed to locate the giac binary");
    }

    my $results=$giac->run('sin(x)+cos(pi)-3');
    print $results."\n";

    $results=$giac->run('mathml(sin(x)+cos(pi)-3)');
    print $results."\n";

    $giac->set_vars({ A=>2 });
    my $results=$giac->run('sin(A)+cos(pi)-3');

METHODS

new

This initiates the object.

This also checks to make sure that giac is in the path. If that check fails, it will die.

    my $giac;
    eval( {
       $giac=$Math::Giac->new;
    } );
    if ( $@ ){
        die("Failed to locate the giac binary");
    }

run

This returns the respected string after putting together a variable list.

The final output is what is returned, or $output[ $#output - 1 ], assuming it is a single line one. Otherwise it works backwards to find a match.

This will remove the " from the start and return of the return, which gets added for with latex or mathml.

This will die on a non-zero exit or no string being specified.

    my $results=$giac->run('sin(x)+cos(pi)-3');
    print $results."\n";

    $results=$giac->run('mathml(sin(x)+cos(pi)-3)');
    print $results."\n";

vars_clear

Removes any set variables.

As long as new was successfully called, this won't error.

    $giac->vars_clear;

vars_set

Sets the variables.

xsThis requires one argument, which is a hash reference.

VARIABLE HANDLING

Lets say the variable hash below is passed.

    {
        A=>1,
        B=>3,
    }

Then the resulting code will be as below.

    A:=1
    B:=3

Then requested item to run is then added to the end. So if we are running 'sin(pi)+A' then we will have the item below.

    A:=1
    B:=3
    sin(pi)+A
