Mat
The Mat object is very useful for matrix-like operations in Hedgehog Script.
- It can be 1 dimensional, 2D, 3D, etc. It can also represent tensors!
To declare one, do the same as you would for an object (by using the new keyword).
Here's an example:
Don't forget to use ( ) to construct it!
info
When constructing a Mat, always have at least 2 layers of brackets. Something like new Mat([1,2,3,4]) is forbidden.
We support many functions for matrices:
Basic summation, multiplication, elementwise-operations, decompositions, processing data and much more.
- It's all there, built-in, easy to use.
However, those functions are located in the "Math" book (top navigation bar). In this section we simply give the basics.
Here are the fundamental properties of Mat objects:
rows, cols, val. Sub-properties include: val.length, val[0].length.
There are vital for operating around a matrix. An example of some properties at play:
tip
Use the property val to transform a Mat into a raw Array:
myMat_raw = myMat.val;
Typical Array functions can now be performed on myMat_raw.
Close to all built in Math functions for Hedgehog Lab work for Arrays, Tensors and Mats.
However, if you only have a normal Array you are limited to Hedgehog Script's Array libraries.
Here is an example of using Mat in a function:
tip
Mat is a powerful tool for representing and operating on matrices.
