Algae    hoch http://algae.sourceforge.net
 
  Beschreibung: Algae is an interpreted language for numerical analysis and matrix processing, similar to Octave or MATLAB. Algae is said to be very fast. It is free software under the GNU General Public License.

Some facts:

  • dynamically typed, interpreted
  • exceptions
  • functions are first-class
  • types: scalars, vectors, matrices, tables(records)
  • C-ish syntax


 Hello World   Michael Neumann 
# Hello World in Algae

printf("Hello World\n");
Gibt "Hello World" auf dem Bildschirm aus.


 Misc   Michael Neumann 
# fill(shape; values)
fill(3,4; 1,2,3,4)   # => 3x4 matrix filled (row-wise) with 1,2,3,4

diag(1,2,3) # 3x3 matix with 1,2,3 on the diagonal

# linspace(a; b; n)
linspace(1;10;100)  creates a vector with 100 elements from 1 to 10

# ident(n)
# creates the nxn identity matrix



 Squares (1)   Michael Neumann 
# Note that functions can be applied to scalars as well as to vectors or matrices
squares = function(x)
{
  return x^2;
}

nums = 1:10:1;    # a vector containing elements from 1 to 10

print( squares(nums) );
# or ...
print( nums^2 );
Gibt die Quadrate von 1 bis 10 aus.


 Squares (2)   Michael Neumann 
for (i in 1:10) {
  printf("%d "; i^2);
}
printf("\n");
Gibt die Quadrate von 1 bis 10 aus.
