WebIn my application, the lists are way bigger, so I am looking for a general way of removing a list of numbers from the original list. My thoughts were to use the following code: DeleteCases [ {1, 2, 4, 70, 11, 20, 56, 79}, {2, 4, 56}] but that didn't work, because the output must be {1, 70, 11, 20, 79} and it isn't. list-manipulation. filtering. WebThe list given in Fourier [list] can be nested to represent an array of data in any number of dimensions. The array of data must be rectangular. If the elements of list are exact numbers, Fourier begins by applying N to them. Fourier [list, {p 1, p 2, …}] is typically equivalent to Extract [Fourier [list], {p 1, p 2, …}].

WebGaussianFilter is a filter commonly used in image processing for smoothing, reducing noise, and computing derivatives of an image. It is a convolution-based filter that uses a Gaussian matrix as its underlying kernel. Gaussian filtering is linear, meaning it replaces each pixel by a linear combination of its neighbors (in this case with weights specified by … WebReverse — reverse a list at any level. RotateLeft, RotateRight — cyclically rotate lists at any depth. Transpose — transpose any collection of levels. ArrayReduce — reduce dimensions of an array by applying a function. ArrayResample — resample an array to higher or lower resolution. ArrayPad — add padding on each side. WebList Manipulation. Lists are central constructs in the Wolfram Language, used to represent collections, arrays, sets, and sequences of all kinds. Lists can have any structure and size and can routinely involve even millions of elements.
