  • Use semi-colon at the end of the line to prevent the output of the operation to be printed to the screen
>> x = 1

x =

     1

vs.

>> x = 1;
>>


Vector and Matrices

  • Use square brackets to define a vector/matrix

x = [1 2 3 4 5]


  • Inside a vector/matrix definition, commas or spaces separate elements row-wise
>> x = [1 2 3 4 5]

is the same as:

>> x = [1,2,3,4,5]

and they both generate a row vector. Semi-colons, instead, separate elements column-wise:

>> x = [1;2;3;4;5]

General tips

  1. Try to vectorize every operation if you can
