Tricks and Shortcuts

*Creating an Array

Comma(,) has to be used to separate the elements(especially when negative numbers are in an array). This removes the ambiguity.

For example:(without comma)
a = [1 2 3; -4*5 -4 6; 7 8 10]
This gives the answer as:
a =  1 2  3
   -24 6
     7 8 10

with comma:
a = [1 2 3; -4*5, -4 6; 7 8 10]
a =  1  2 3
   -20 -4 6
     7  8 10

*Notations

The unit operators work for simple or matrix parameters on both sides. This makes |-| be available for non-unit based subtraction. This is possibly a better notation.
To do unit based subtractions, do

A=[1m 2m];
B=[4m 5m];
c=A<->B
c = [-3m -3m]

A=[1m 2m];
B=[4m 5m];
c=A|-|B
c = [-3 -3]

*Creating an Array with an interval

An array can be created within a given interval using this notation. Brackets() are important.

xmin = 1
xmax = 2
dx = 0.2
x = [(xmin-dx)..(xmax+dx)..(dx)];
x = [0.8 1 1.2000000000000002 1.4000000000000001 1.6 1.8 2 2.2]
