1. Plot Function Draw a Curve Function format: plot(x,y), where x and y are coordinate vectors. Function purpose: To draw a curve with vector x as the x-axis and y as the y-axis. Draw Multiple Curves in the Same Plot plot(x,y1,x,y2,x,y3) uses the common vector x for the x-axis, and y1, y2, y3 for the … Read more
The graphing calculator is a niche market, with the main players being Casio and TI (Texas Instruments). Currently, the major issues with these two giants are their lack of aesthetic appeal, slow hardware and software iterations, and relatively closed systems. The NumWorks graphing calculator is quite impressive, offering a high level of playability, and its … Read more
