Matrix Operations Example

(See the README.md file in the upper level 'examples' directory for more information about examples.)

This example demonstrates how to use Mat class functionality from esp-dsp library. Example does the following steps:

Initialize a matrix A and matirx x
Calculate matrix b: b = A*x
Find roots x1_: A*x1_ = b, with different methods
Print result

How to use example

Hardware required

This example does not require any special hardware, and can be run on any common development board.

Configure the project

Under Component Config ---> DSP Library ---> DSP Optimization, it's possible to choose either the optimized or ANSI implementation, to compare them.

Build and flash

Build the project and flash it to the board, then run monitor tool to view serial output (replace PORT with serial port name):

idf.py -p PORT flash monitor

(To exit the serial monitor, type Ctrl-].)

See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.

Example output

Here is an typical example console output.

I (215) main: Start Example.
I (215) main: Original vector x:
0
1
2
I (215) main: Solve result:
0
1
2
I (215) main: Roots result:
0
1
2
I (215) main: End Example.
