Is there any way to get MathPad to put out vector plots?
Vector plots aren’t built in. I’ve thought about adding it but I rarely have any use for them. They tend to be useful only when looking at things with small dynamic range that vary smoothly. This doesn’t mean that there aren’t things like that worth plotting. Using the image command to plot various combinations of x,y angle and magnitude against each other is often helpful. Of course it’s possible to get MathPad to plot anything. When you plot {x,y} arrays it will lift the pen for an undefined point. That means you can draw anything by generating the desired sequence of {x,y} coordinates. A crude vector plot is pretty easy to set up. The only tricky part is all the little mods and +1s needed to generate the correct index values. Putting nice little arrowheads on the vectors would be tougher. Here is an example that shows the basic idea. ————- vector plot ————- — example array of vectors vec= {{.1,.05},{.2,.3},{.2,.4},{.3,.5},{-.5,.4},{-.6,.2}, {-.7,.1},{-.7,-.1},{-.8,-
