- Clone the current repository: $ git clone
- Go to the cloned directory: $ cd
- Find the sha1 of the commit to pull. For stash, click on the commit and look at the address bar. It will be the last part of the url. For example, the sha1 for http://mystash.arwan.com/repos/arwanproj/commits/0b004fdb420838ca04c15b25ad2e0b66a5693963 will be 0b004fdb420838ca04c15b25ad2e0b66a5693963
- Fetch the version based on the sha1 number found: $ git fetch origin
- Checkout: $ git checkout FETCH_HEAD
IF Condition in Wolfram Mathematica The syntax is as follows xxxxxxxxxx If [ condition , what to do if true , what to do if false ] Some examples Example 1. Simple command x x = - 3 ; If [ x < 0 , - x , x ] 3 Example 2. If condition in a function abs [ x_ ] := If [ x < 0 , - x , x ] abs /@ { - 3 , 2 , 0 , - 2 } { 3 , 2 , 0 , 2 } For in Wolfram Mathematica The syntax is as follows For [ start , test , inc , what to do ] Some examples Example 1. Simple Loop xxxxxxxxxx For [ i = 0 , i < 4 , i ++, Print [ i ]] 0 1 2 3 Example 2. Another simple loop For [ i = 10 , i > 0 , i --, Print [ i ]] 10 9 8 7 6 5 4 3 2 1 Example 3. Print list a = { 10 , 3 , 9 , 2 } For [ i = 1 , i < 5 , i ++, Print [ a [[ i ]]]] 10 3 9 2
