SUMMARY

The mod(x,y) command in MATLAB calculates the modulus, which is the remainder of the division of x by y. For instance, mod(4,2) returns 0, indicating that 4 is divisible by 2, while mod(9,4) returns 1, showing that 9 divided by 4 leaves a remainder of 1. This command is essential for determining divisibility, as demonstrated in the discussion where the condition mod(R,D)=0 is used to check if R is divisible by D, specifically when D=3. Understanding the mod function is crucial for writing efficient scripts in MATLAB.

Hello all, i am trying to write a script file that will only print if R is divisible by D where D=3
I wrote a loop statement with the condition being fix(R/D)=R/D this works fine but there is another way that the book does it. The book uses mod(R,D)=0 as the condition. I tried typing in help mod but the explanation that MATLAB gave was extreamly confusing, can anyone tell me what the command mod(x,y) says...what does the (x,y) mean...thanks in adnvance.

mod is the modulus of command. A modulus is essentially the remainder of a division process. Here's a few examples:

4/2=2 R=0--2 goes evenly into 4 thus there is no remainder.

so, mod(4,2) would give a result of 0

9/4=2 R=1--4 goes into 9 twice leaving a remainder of 1

so, mod(9,4) would give a result of 1.

Mod commands are common to most (I can't think of a language that doesn't include this command though different syntax is used) and are very powerful/useful tools.

Hope this helped. Good luck.
 
wow...thanks for the example, it hit the spot!
