+# 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:
+
+1. Initialize a matrix A and matrix x
+2. Calculate matrix b: b = A*x
+3. Find roots x1_: A*x1_ = b, with different methods
+4. 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.
+
+```
