Every variable in MATLAB® is an array that can hold many numbers. When you want to access selected elements of an array, use indexing. For example, consider the 4-by-4 matrixA: A = [1 2 3 4; 5 6 7 8; 9 10 11 12; 13 14 15 16] ...
用True和False代替整数做index,最常见的用途是获取满足条件的元素。另外,由于theano的tensor variable并没有boolean类型,所以boolean array indexing只适用于ndarray。 比较简单,举个例子就能明白,比如,获得ndarray中大于11的元素: a=np.array([[1,2,3,4,5],[6,7,8,9,10],[11,12,13,14,15]])# 一个3行...
MATLAB always attempts to apply the dot indexing operation to the temporary variable, even if the function returns a variable for which dot indexing is not defined. For example, if you try to index into the matrix created by magic(3), then you get an error. magic(3).field Dot indexing ...
Code generation supports growing either an array or a cell array in your MATLAB® code by using end + 1 indexing. To use this functionality, make sure that the code generation configuration property EnableVariableSizing or the corresponding setting Enable variable-sizing in the MATLAB Coder™ ...
