# Tick labels in a matrix plot

I want to plot the following matrix `m`

with k and l in {-2, ..., 2}:

```
m = [[k+l for k in range(-2,3)] for l in range(-2,3)]
```

with `matrix_plot`

:

```
m_plot = matrix_plot(m, origin='lower')
```

The ticks on both axes are automatically set to {0 , ... , 5}, but I want the ticks to be {-2, -1, 0, 1, 2} on both axes. I could not figure out how to do this.
