## Matrix Visualizer
2+
3+
### Introduction
4+
5+
The Matrix Visualizer shows the contents of an array as a matrix, a number of rows and an number of columns.
6+
7+
The Matrix Visualizer is made up of 3 main parts:
8+
9+
* Input parameters
10+
* Values table
11+
* Statistic information
12+
13+
### Input parameters
14+
15+
This part of the Visualizer specifies the array to view. Here are the details for an array.
16+
17+
* Variable name of the array. The name name should resolve to an address.
18+
* Number of rows and columns. The total length of the array is determined from this.
19+
* Array offset. How many elements to initially skip. Default 0 (start at the begining of the array).
20+
* Array stride. How the elements are accessed in the array. Default 1 (use every element). 2 would access every second element.
21+
* Array data type.
22+
* Refresh.
23+
24+
By having array offset and array stride, it's possible to handle oddly constructed arrays.
25+
26+
### Values table
27+
28+
This part of the Visualizer shows the array's values as a matrix. The number of rows and number of columns reflect the values
29+
entered in the input parameters.
30+
31+
Note, the array offset and array stride is taken into account.
32+
33+
### Statistic information
34+
35+
These statistical values are calculated from the array values.
36+
37+
* Count of values
38+
* Count of number of rows
39+
* Count of number of columns
40+
* Minimum value of values
41+
* Maximum value of values
42+
* Sum of values
43+
* Average value
44+
* Median value
45+
* RMS value
46+
47+
