Matrix Display

# Summary

• Plugin name : Matrix Display
• Version : 1.0
• Author : Laurent Bonnet
• Company : INRIA/IRISA
• Short description : Display a streamed matrix

# Description

The streamed matrix can be visualized using a table of values and/or a color gradient.

This box displays an input matrix in a table of gradient-colored squares. WARNING : The color gradient is centered (50%) at the value 0. The limits of colors match the minimum and maximum values, ever received or in real time if the corresponding setting is set. These values can evolve symmetrically, using the maximum absolute value.

# Inputs

## 1. Matrix

The matrix to display.

• Type identifier : Streamed matrix (0x544a003e, 0x6dcba5f6)

# Settings

## 1. Color gradient

The color gradient used.

• Type identifier : (0x3d3c7c7f, 0xef0e7129)
• Default value : [ 0:2,36,58; 50:100,100,100; 100:83,17,20 ]

## 2. Steps

The number of color steps used in the gradient. The more you have steps, the smoother the gradient will be .

• Type identifier : Integer (0x007deef9, 0x2f3e95c6)
• Default value : [ 100 ]

## 3. Symetric min/max

This parameter determines if the minimum and maximum values, matching the 0% and 100% color in the gradient, should change symmetrically using the maximum absolute value and its opposite.

• Type identifier : Boolean (0x2cdb2f0b, 0x12f231ea)
• Default value : [ false ]

## 4. Real time min/max

This parameter determines if the minimum and maximum values, matching the 0% and 100% color in the gradient, should be recomputed for each matrix received.

• Type identifier : Boolean (0x2cdb2f0b, 0x12f231ea)
• Default value : [ false ]

# Examples

Here is an example using a BoxAlgorithm_ConfusionMatrix box that computes confusion matrix from classifier results.
