/CS /DeviceRGB is interpreted as {{1,2},{3,4}}: When an input evaluates to TableForm[expr], TableForm does not appear in the output: Out is assigned the value {{1,2},{3,4}}, not TableForm[{{1,2},{3,4}}]: Even when an output omits TableForm from the top level, it is not stripped from subexpressions: The output does not have TableForm in it: However, the variable e does have TableForm in it, which may affect subsequent evaluations: The determinant is not evaluated due to the intervening TableForm: Assign variables first and then apply TableForm to the result to maintain computability: MatrixForm Grid TextGrid GraphicsGrid TableView ArrayPlot PaddedForm.

So it's a simple matter to modify only that column: will apply f to each element of the nth column of mat. Try Thanks, but this is not the answer I I wanted, probably as I did not explain it well. To begin, be careful when using TableForm. Chain Rule 5.3 then makes it easy to differentiate g(x, y) = 0 with respect to x: (1)0 = d dx [g(x, y)] =g(x, y) ( x x , y x ) = g(x, y) (1, y'(x)). When defining functions in Mathematica, the right subscripted underscore character must appear with the initial occurrence of each variable to the left of the := sign.

I tested it and it works perfectly. Simone. % % But even from the graph, the precise value of k for that curve is not clear. The coordinates of vectors are in braces, with commas between them. /Type /XObject I looked up the possible options for TableForm, but I could not find a relevant one.

Merely define your function that you are using before actually running this code (you must call it f [x_]:= function of x you want). It also contains the assignement at the very end. To create a new file and put an expression (mathematica output) in the file wiping out previous entriesin the file: expr >>myfile (same as Put[data, "myfile"])To append an expression to an existing file: expr >>>myfile (same as PutAppend[data, "myfile"]) endobj Thanks. )@wy?U>{u.t%#;!mh$mmU.vi What should I follow, if two altimeters show different altitudes? Software engine implementing the Wolfram Language. Just modify via a variable: It does, yes. evaluate f at every candidate (x, y) that solves the system (3) the largest value that results is the maximum of f subject to g(x, y)= 0 the smallest resulting value is the minimum of f subject to the constraint.

How a top-ranked engineering school reimagined CS curriculum (Ep. Looking for job perks? Wolfram Language & System Documentation Center. Comments? The key point is that for any value k, the function f assumes the value k precisely on the level curve f(x, y) = k. To find the maximum or minimum value of f on the curve g(x, y) = 0, it is thus enough to plot the level curves of f and find the largest and smallest values of k for which the curve g(x, y) = 0 intersects some level curve f(x, y) = k. The following figure illustrates the idea for the problem from Example 10.4 of Section 4.10: find the maximum value of f over the curve 2 x 4 + 3 y 4 = 32, if the formula for f is f(x, y) = ( x 2 + y 2 ) 1 / 2 . Here is data on objects and their dimensions: Use the Alignment option to specify how items in columns should align: Add a row of column headings to the grid.
