## How To Calculate Determinant Value Of A Matrix In Matlab®?

```
>> a = [1 3 5;7 8 11;100 1 4];
d = det(a)
e = det(a).*5
f = det(a)+3
d =
-728.0000
e =
-3.6400e+03
f =
-725.0000
>>
```

To calculate determinant values of matrices in Matlab®, you need to use the ‘det(a)’ command. Here some examples about use of this command in Matlab®;

‘a’ is the main matrix that we wish to calculate its determinant value in Matlab® as shown above.

‘d’is the calculated determinant value of ‘a’ matrix with det(a).

At ‘e’, the determinant value is multiplied by 5 which shows you can do mathematical multiplications with determinant values in Matlab®.

In ‘f’, the determinant value is added with 3 which means you can do basic addition or subtraction calculations in Matlab® with ‘det()’ code.

## Conclusion

Here is very basic to calculate determinant values of matrices in Matlab® with the ‘det()’ command.

Do not forget to leave your comments and questions below about the use of the ‘det()’ command in Matlab® below.
