# How To Obtain Ones Matrices In MatLab®(Illustrated Expression)

In mathematical calculations in Matlab®, matrices are generally used. So there are lots of easy matrices generating commands in Matlab®. Sometimes users needed to obtain big matrices that include only the number of 1 in all elements inside it. This kind of matrix could be generated by a special command called ‘ones’. This is the command that the users could obtain matrices that comprises only the number ‘1’ inside them. You can follow the basic example below to understand how the ‘ones’ code works in Matlab®.

## How The ‘Ones’ Is Used In Matlab®?

``````>> v = ones(2,3)
z = 5.*v
d = 5./ones(4,5)

v =

1     1     1
1     1     1

z =

5     5     5
5     5     5

d =

5     5     5     5     5
5     5     5     5     5
5     5     5     5     5
5     5     5     5     5

>> ``````

As you can see above, we gave three examples about the usage of the ‘ones’ command in Matlab®. The general use of the ‘ones’ command in Matlab® is like the v variable above. You just type ones then the dimensions of your matrix inside the parentheses right after it. You can see the v variable that includes only the number of 1 inside it.

Also, you can make mathematical calculations as shown with the z variable above. We just multiplied v with 5 then you can see all the numbers are multiplied with 5 in Matlab®.

## Conclusion

Also, you can directly do mathematical calculations with ‘ones’ code as shown by the d variable. So you can obtain various matrices by using the ‘ones()’ command as shown above in Matlab®.
