Linear Transformations

Linear Transform Operations

inv(A) computes the inverse of a square matrix, unless it is a singular matrix of course. This function is prone to the same error as the det() function, make sure to always check and understand your answer! Full Documentation
```
  inv(A)
```
null(A,”r”) computes the null space of a matrix A, the second argument “r” returns the null space on a rational basis. Full Documentation
```
  A = magic(4);
  null(A,"r")
```
Plotting

IMPORTANT plotv requires the Deep learning toolbox to work. Make sure it is installed before trying to use it.
plotv(M) generates 2 Dimensional plot of vectors from the origin, the input argument M is a matrix that contains the x components of the vectors in the first row and the second row contains the y components of the vectors: M = [x1 x2; y1 y2]. Full Documentation
```
  M = [2 3 5; 1 2 3];
  plotv(M)
```
