- Required python in the system at least the 3 version. If you install python do not miss to adding into the environment variables. Also required to install matplotlib:
pip install matplotlib - Use x64 architecture if you build C++
Simplest C++ plotting library --> matplotlib-cpp
##Tips and Tricks
Measure execution time with high precision
Computational complexity of mathematical operations
| Complexity | |
|---|---|
| Addition | O(n) |
| Subtraction | O(n) |
| Multiplication | O(n^2) |
| Division | O(n^2) |
- Combine constants where we can
- Instead of use simple math expression like from math library for example pow(x,2) use
x*x. Integer quotient use likex*x*x*x. Not cute but effective. - Instead of dividing use the inverse of denominator like
vector[i] / constant --> vector[i] * constatn2 where constant2 = 1.0 / constatnt1
Check this library. Maybe it is faster than Eigen or vanilla C++ NumPy to NumCpp
