| Hi: I cannot get the ListLinePlot at the bottom on the attached notebook to display the meanPath and the lowerBoundPath on the simulation plot. I have tried a bunch of different things, but nothing seems to work. Thanks so much, Mitch... |
| Hi Community Member, I am trying to import a simple Excel spreadsheet containing a date stamp column and a data column of closing prices. While the import appears successful, the resulting TimeSeries object seems to list the closing prices as the... |
| I am trying to calculate the m and b values as a best fit to the equation of the line of y=mx + b - see attached notebook. In the first section of the notebook, I performed the detail calculations manually to obtain the variables of m = 1.1 and... |
| Hi; I am trying to plot a progression of time periods for a Predator - Prey model using the function ParametricPlot with constants, Eigenvalues (raised to k powers and Eigenvectors - see attached notebook. However, I am having trouble getting any... |
| Hi; I am trying to use the function Solve[] and Eigenvalues[] to solve for an unknown p variable as follows: SolveValues[Eigenvalues[{{6/10, 1/2}, {-p, 6/5}}] == {1,}, p] The problem is that the function Eigenvalues[] returns 2 values... |
| My end goal is to visualize how the vector plot changes in real time by manipulating one of the input variables. I can change the -7 input value manually and press Enter to get a different vector plot. However, I cannot seem to get the same results... |
| Hi; Please see attached notebook. Is there a better way to add text to Primitives such as Arrows in Graphics functions? I tried using the function PlotLegends which did not work ether. The following code does not generate the Blue Arrow Text -... |
| In order to get a better understanding of Eigenvectors and Eigenvalues, I am plotting both the given and calculated the vectors geometrically using Graphics[] and running into problems - see attached notebook. 1. The calculated eigenvectors... |
| Hi I am having trouble looking up the closing price of a mutual fund (for example "WHIAX") - see attached. I have tried several different methods all without success and would certainly appreciate any help. Thanks, Mitch Sandlin &[Wolfram... |
| Hi Mathematica Expert; In order to get a better understanding of 3 sets of data, I created a Venn diagram. Now, I would like to convert the Venn diagram into a statement that describes the sets of data, which I am having trouble - see attached... |
