If your graphics are not too complex, we can deploy them to the cloud and get an interactive, rotatable object. Try this: CloudDeploy[ Plot3D[Sin[x^2 + y^2], {x, -2, 2}, {y, -2, 2}] ] You'll get …

You can edit the notebook's stylesheet and change the Print style. Choose Format -> Edit Stylesheet... Add a new cell. Reveal the cell expression (Command-Shift-E). Change to the following or simi …

As I understand, you want to generate some C code which represents an array of 3D coordinates, created with SpherePoints. You can do this with string processing and CForm. Example: coordsToC3D[coord_ …

Before version 6, graphics did not display immediately after evauating the (inert) Graphics[] expression. They could be shown using the Show command (it was a side-effect of Show). … Edit: There are still a number of display mechanisms that use DisplayFunction. One is <<Version5`Graphics` mentioned by @Mr.Wizard. …

You could do it like this: arr = {{2, 1, 0, 0}, {1, 0, 0}, {0, 0}, {0}}; With[ {r = Riffle[#, ""] & /@ arr}, {l = Max[Length /@ r]}, Grid[CenterArray[#, l, ""] & /@ r] ] CenterArray is new in …

I see three ways: Copy and paste everything into a new notebook (to ensure we don't destroy the output for good). Then select Cell -> Delete All Output from the menu. alt-click (⌥-click on a Mac) o …

Here are three progressively more intrusive steps to troubleshoot Mathematica. Hold down Shift-Control (Shift-Command on Mac) while starting Mathematica, as described here. If this didn't fix the …

This is not a bug. It is a well known limitation when running the kernel on a headless server on Linux. Some operations require the Front End. Importing TeX is such an operation. The Front End req …

For equations: Copy as MathML, then paste into Word. This will create a proper equation in Word. Should work with Word versions that support the new-style equation editor, both on Windows and Mac. …

For simply transposing a ragged array, see Transpose uneven lists For displaying various transpositions both as upper or lower triangular formats, pad the array before display: Transpose@PadRight[ragged …

You can use MaTeX to get $\LaTeX$ formatting directly: MaTeX["\\frac{1}{N}{\\sum _{i=1}^N \\frac{\\tilde{x}_j^i(k|k)}{\\sqrt{P_{\\text{jj}} (k|k)}}}"] MaTeX can also be applied directly to Mathem …

Update: According to the OP's comment, he is looking for a solution that works in Mathematica 7. MaTeX requires Mathematica 10. I am leaving this answer here in case others find it useful, but note …

Based on @Mike's answer here, add ScriptLevel -> 1 to Style. Mathematica uses the ScriptLevel value to determine when it should decrease the font size in equations. The script level increases with …
