TableForm. To learn more, see our tips on writing great answers. Using Mathematica on Lagrange-multiplier ProblemsCopyright 1997, 1998, 2000 by James F. Hurley, Department of Mathematics, University of Connecticut, Storrs, CT 06269-3009. % To find the points of intersection of the constraint curve 2 x 4 + 3 y 4 = 32 and the level curves of the function f, it might be feasible to solve g(x, y) = 0 for y as a function of x. It probably just needs some Map or MapAt command, maybe combined with a Transpose in order to apply to rows instead of columns - but I can't figure out the correct syntax for addressing an entire column (or row).. So x={1,2,3,4}, y={10,20,30} and f(x,y) are the remaining data. In the definition below, I've added 0 to the first element of the data: w[n_]:=(2-(-1))/n; c[k_]:=(-1+(1/2)*w[n])+(k-1)w[n]; h[k_]:=5-c[k]^2; Table[GeneralizedBarChart[Table[{c[k], h[k], w[n]},{k, 1, n}]],{n, 5, 15, 5}] 3.

You really don't need to know the value of , so if possible you can eliminate and solve for all pairs (x, y) that satisfy (3). A multiplication table for the numbers 1 through 7. Let's say I want to make a title "Bravo" on top of the table(which is center-aligned). This will generate a table without a title. 2 0 obj To produce the figure, hit the Enter key (at the lower right of the keyboard) after the last command of the following Mathematica routine.

Wolfram Description If you wish to Export a table from Mathematica and maintain the table formatting you will need to use a few tricks. Dataset gives a quick, left-aligned view of tabular data in an array: When the data is a list of associations, Dataset displays the association keys as column headings: For detailed control of formatting, use Grid. stream Actually I just want to multiply all elements in that column with a scalar, but the application of a general function would be fine as well. Yeah, that works. Curated computable knowledge powering Wolfram|Alpha. Make the headings bold and extend the second heading into the third and fourth columns with SpanFromLeft: Add a column of row headings to the grid.

Note: To remove quotes in title you can use: Update: Post-processing the output of Jen's method to center the label and remove the divider line: Here is another approach using only the functionality of TableForm itself: This nests the list deep enough inside {{ }} so that the column labels provided by TableHeadings are applied only to a single column containing the actual table.

Merely define your function that you are using before actually running this code (you must call it f [x_]:= function of x you want). I am aware of the use of TableForm, and I don't want to add an extra in the first row. Suppose then that g y != 0, so that by the implicit-function theorem the constraint equation g(x, y) = 0 defines y as a differentiable function of x. Instant deployment across cloud, desktop, mobile, and more. Technology-enabling science of the computational universe. 1988. In your second graph you see that the data coordinates are 1 to 5 for x and 1 to 5 for y. So it's a simple matter to modify only that column: will apply f to each element of the nth column of mat. /Height 557 But your solution is way more elegant and flexible. where the first line is the x axis, but the y column is the first number of the following lines Elegant, readable, and works with in-line code, e.g., when manipulating a list before plotting it, like multiplying the x-column by two: ListPlot[Map[MapAt[Function[x, 2 x], #, 1] &, list]], Mathematica: How to apply function to a certain column of a table.
