WebGive a number which shows how many times point1 from List1 satisfies the criteria. In order to clarify the problem : first element of List1 includes two points : { {4, -1}, {5, -2}} point1 = {4, -1} and point2 = {5, -2}. x1 = 4 < x2 = 5 and y1 = -1 > y2 = -2. So point {5, -2} dominates point {4, -1} : ( 5>4 and -2<-1 ) WebLength—Wolfram Language Documentation. Wolfram Language & System Documentation Center. BUILT-IN SYMBOL. See Also.

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.
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 … Web$\begingroup$ Thanks, but deleting the rules from the the list to make them such that they don't contain g[1] -> 0 and h[3] -> 0 is not what I wanted. I meant to select all the lists which don't contain g[1]->0 in the first place. $\endgroup$ –
