When you have numerical data, it is often convenient to find a simple formula that approximates it. For example, you can try to "fit" a line or curve through the points in ...

The history of an interactive Mathematica computation is both maintained in a fully editable Mathematica notebook, and is stored symbolically in a sequence of In and Out ...

Plain text file. Universal format for storage and exchange of textual information. Represents text as a sequence of characters and line separators. Stores characters as ...

GraphicsComplex[{pt_1, pt_2, ...}, data] represents a graphics complex in which coordinates given as integers i in graphics primitives in data are taken to be pt_i.

Mathematica provides detailed symbolic control over all aspects of text layout. Placing separate blocks or paragraphs in separate cells also immediately allows Mathematica's ...

EdgeDetect[image] finds edges in image and returns the result as a binary image.EdgeDetect[image, r] finds edges at the scale of the specified pixel range r.EdgeDetect[image, ...

ListContourPlot[array] generates a contour plot from an array of height values. ListContourPlot[{{x_1, y_1, f_1}, {x_2, y_2, f_2}, ...}] generates a contour plot from values ...

Thickness[r] is a graphics directive which specifies that lines which follow are to be drawn with thickness r. The thickness r is given as a fraction of the horizontal plot ...

StreamPlot[{v_x, v_y}, {x, x_min, x_max}, {y, y_min, y_max}] generates a stream plot of the vector field {v_x, v_y} as a function of x and y. StreamPlot[{{v_x, v_y}, {w_x, ...
