The new solution framework for Ordinary Differential Equations (ODEs) in MATLAB R2023b
Along with linear algebra, one of the iconic features of MATLAB in my mind is how it handles ordinary differential equations (ODEs). ODEs have been part of MATLAB almost since the very beginning.One of the features of how MATLAB traditionally allows users to solve ODEs is that it provides a suite of functions. For many years, there were 7

MATLAB Mini Hack Winners - Week 4
In Week 4, we invited the MATLAB Graphics team to help judge the entries. As the authors of the MATLAB functions used in every entry, they made sure every entry selected used a unique graphics function or technique from the other winners. Here are their choices:
1. Umbrellas by Shanshan Wang
Comment: Cool use of 'swarmchart' to make art from distributions; Only use of one of our newest graphics functions
2. Happy Sheep by Victoria
Comment: Cute!
3. Alien Giant by Jenny Bosten
Comment: Original idea, well textured, and efficient code
4. 3D Ultrasound by Adam Danz
Comment: Replicate source material very well. Effective use of lighting and material. Overall, impressive to produce this image given the limitation
5. Sunset in the Savanna by Sebastian Kraemer
Comment: Looks cool! Nice mix of 'image', 'fill' and 'scatter' commands.
6. Night Flight by Ratul Das
Comment: original; clever use of 'rectangle'
7. Lantern #2 by Tim
Comment: Nice use of 'getframe' to create a texture for 'surf' for a compelling picture
8. Geometric Design (6) by Daniel Pereira
Comment: Looks like some walls at MathWorks
9. Rosette 1313 by Alex P
Comment: Looks cool! Nice use of 'pcolor'
10. Mandelbrot contour by Sumihiro
Comment: Best use of contour!
11. Aim High by Murty PLN
Comment: Largest number of unique graphics objects for the Mini Hack (plot, patch,stairs,stem,text)
In the spirit of Mini Hack, the MATLAB Graphics team also created several cool graphs about the contest. Facing a similar space limit, I have picked only 2.
