Otherwise, you could have an infinite loop that continues to iterate endlessly this will crash your Mathematica script. These loops need to eventually terminate when the condition becomes false.
If all 3 criteria above are met, then the body of the loop will execute.įinally, please pay attention when writing the condition that is tested by the loop. You have to change the start using incr (increase or decrease its value, for example) in the loop. You have to test the condition during each iteration of the loop. You need to initialize the start of the condition before the loop begins. When creating these types of loops, it is important to remember that: If no Return is specified, then the value returned is null. Then, it exits the loop after finding the first specific value. 
Return statement- can return a specific value calculated by the loop. Continue statement- the loop exits the evaluation of the body and continues by computing the increment, incr. Let’s provide details about the body of the loop. 
The next lines of code after the loop will be processed by Mathematica. Otherwise, if the condition is false, then the body is not evaluated and the loop will exit out.
In addition to this, it contains a body of statements.įor – executes start, then repeatedly evaluates the body and incr until the condition becomes false.Īs long as the condition is true, then the body will be executed again and again. It consists of the for statement (which evaluates a condition with a start value and an increment, incr).
while loops (discussed in more detail in while loop Mathematica post). do loops (for do loop information, you can read the article about do loops in Mathematica) a do loop is logically similar to a for loop. There are 5 kinds of loops in Mathematica: In this tutorial, you will learn about the Mathematica for loop and you will apply it to several examples. One type of loop statement is the for loop. They are very useful when you need to execute a section of the program repeatedly. Loops are widely used in Mathematica and other languages.
