I wanted to find the least common multiple of a group of more than two numbers. Matlab's built in lcm function does not have this capability. It accepts two integer inputs, but cannot handle more. So I wrote lcms. lcms uses the prime factorization method to determine the least common multiple of a set of numbers. It is pretty simple.
z = lcms(numberArray)
This function accepts any n-dimensional array of natural numbers as input (Zeros do not change the output of the program).
Example usage of lcms:
>> lcms([1 2 3 4 6 8 12 24])
>> A = [5 6; 8 10; 12 14]
Having a 0 in your input array will not affect the program.
lcms([0 1 2 3]) returns a 6.
lcms([1 2 3]) also returns a 6.
Having negative numbers or non-integer types in your input error will result in an error message.
lcms([2.5 3 2 8]) results in an error.
lcms([5 2 -3 1]) results in an error.
Input is more robust. Now you use any n-dimensional array instead of a row vector.
Error behavior is more clear.
