 =====Octave syntax and library overview=====
+====plotting====
+<code matlab>
+h = [1,2,3,4,5];
+plot(h);
+xlabel("some numbers");
+print("myfile.pdf", "-dpdf");
+</code>
+This code plots a a vector with a label on the x-axis, and exports it to a pdf file.
+====function====
+<code matlab>
+function retval = myfunction(param1, param2)
+  retval = param1 + param2;
+end;
+</code>
+====strings====
+<code matlab>
+mystring = 'hello world'; % create string
+sizeof(mystring) % get length of string
+mystrilyng2 = [ mystring, 'fisk']; % concatenate two strings
+</code>
+sizeof on works in octave. in matlab the length of a string cannot be obtained!
+====string array====
+<code matlab>
+myemptyarray = {}; % create empty string array.
+myarray = { 'hello', 'world' }; % create array with two strings.
+myarray(1) % prints 'hello'
+myarray(3) = 'blah'; %inserts another string into the array.
+sizeof(myarray) % get number of elements
+sizeof(myarray(1)) %get length of first string
+% Iterate strings in string array
+for str = myarray
+  disp(str)
+end
+</code>
+Note: Arrays are 1-based, not 0-based as they usually are in real programming languages.
+Note: sizeof is an octave-only function. size can be used to get the array size in matlab.

+Note: In matlab the ''endswitch'' should be replaced by ''end''
