# Interpolate proc (matrix)

Source: https://ref.dm-lang.org/matrix/proc/Interpolate

### Format
> `Interpolate(Matrix2, t)`

### Args
- `Matrix2`: Another matrix
- `t`: The interpolation factor


Calculates and returns a new matrix between src and Matrix2. If t is 0.5, then the result will be exactly halfway between both matrices.

There are many ways to interpolate matrices. Whenever possible, DM will interpolate by doing scaling and/or shearing first, then rotation, then translation. This is done by trying to find the angle of rotation of each matrix first; a rotation of 180° is counted as a flip rather than a rotation.

It is not strictly necessary for t to be between 0 and 1. Using a value out of bounds will extrapolate a matrix, continuing the change as far as t.
