periodic symbolic matlab function
显示 更早的评论
say I want to make a symbolic function (I mean a function of a symbolic variable x), but it's periodic. Imagine a rectangle that repeats itself along the x axis. But I want it symbolic, not in function of an array x. How to implement it? I can use a for loop but the loop is limited! And there is no such thing as "for i=1:inf"

xm = mod(x,AppropriatePeriod);
and then use xm instead of x in your formula

Take the implicit example
ezplot('x^2-y^4')
and modify to
ezplot('mod(x,8)^2-y^4')
to get it to repeat every 8
