Binary singleton expansion function
Webbsxfun是一个matlab自版本R2007a来就提供的一个函数，作用是”applies an element-by-element binary operation to arrays a and b, with singleton expansion enabled.”. 举个例 … WebOne option is to use the repmat() function we saw earlier to replicate the vector so that it is the same size as the matrix and then subtract. However, a better option (in terms of speed, memory, and arguably readability too) is to use the bsxfun() function (bsx stands for binary singleton expansion).

WebOct 17, 2012 · bsxfun will replicate the input arrays along their "singleton dimensions", i.e., the dimensions along which the size of the array is 1, … WebNov 1, 2024 · Once more, the binary singleton expansion function is used to transform the test data by using the mean face. These transformed train and test data are then optimized for better classification results. 5. Results and Discussion. This section describes in detail the results of the experiment and the analysis of the results.
WebDec 10, 2016 · bsxfun can be used with N -dimensional arrays, and it will expand their singleton dimensions. But it works element-wise. If you want a function that does some "aggregating" operation along rows, as in your example, bsxfun can only do the element-wise part (with singleton expansion). WebUseful function: bsxfun — Many examples use bsxfun BSXFUN Binary Singleton Expansion Function C = BSXFUN(FUNC,A,B) applies the element-by-element binary operation specified by the function handle FUNC to arrays A and B, with singleton expansion enabled.

WebMar 30, 2016 · The reason we need this is because otherwise, as you say, the binary expansion is not unique. An example of this is $1/2=0+1/4+1/8+....$ This function is not a bijection, merely an injection. Its image is the set of all binary sequences with an infinite number of zeros. WebOct 29, 2013 · BINARY SINGLETON EXPANSION. bsxfun is used to effecitively expand the vectors without physically using memory via a built-in for-loop. function P = BSXFun (v1, …
WebFeynman integration, is mainly carried out by the MATAB function BSXFUN (binary singleton expansion function), which was first introduced in March 2007 in version R2007a of MATLAB.
