| Hello everyone, I am trying to calculate a Product, P1, that is a function of NIntegrate. This product is performed over j terms, where j is the number of elements in the list entitled Times1. a = 3/100; b = d = 1; c = 1/2; k = HMax = 2000;... |
| Please delete this question when possible. I asked the wrong question. Apologies for the inconvenience/confusion! |
| Hello everyone, I have a function, x12(t), that I solved for using NDSolve. I am hoping to find all of the intervals of time for which x12(t) |
| Hello everyone, I am trying to plot the function below, but only for values of t = 0, 10, 20, 30, etc. Is there an efficient way to control how many points your plot is comprised of? Any suggestions would be greatly appreciated! Alex f =... |
| Hello everyone, I am trying to use FindRoot to identify all of the values of t for which a function y2(t) equals a particular value (YCritical). When I try this, however, FindRoot either gives the same point for different initial values of t or it... |
| Hello everyone, I have an ODE (y3) for which I am trying to find the minimum that occurs after the first maximum. To do this, I am hoping to use FindMaximum to find the time (T) at which the first maximum occurs and subsequently use FindMinimum to... |
| Hello everyone, I am trying to evaluate a function over a range of input parameters and put each output into a common list. For instance, if we have a function f(a) = Exp[-a]*1000, I am hoping to evaluate the function over the range [0,1] and... |
| Hello everyone, I am trying to put all of the extrema of an NDSolve output into a single list. Specifically, I am hoping to have the extrema listed in order. For instance, in the case of an oscillatory system, I would hope to have a list like the... |
| Hello everyone, Broadly, I am trying to subtract two lists of unequal length. More specifically, I am hoping to find a way to determine which list has the least number of elements (N) and subsequently find the absolute difference between the first... |
| Hello, I am trying to use the interpolating function generated by NDSolve to calculate the time at which the function reaches a value of 1. I tried the following code: q = 3/100 c = 1/2 b = d = 1 k = G = 20000 g = 1 ... |
