You can assign an object to an array of objects of the same class, or an uninitialized variable: newArray(3,4) = D; Arrays of objects behave much like numeric arrays in MATLAB. You do not need to implement any special methods to provide standard array behavior with your class. For ge...
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...
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™ ...
For each variable in a Dataset or DataArray (the array and its coordinates): Broadcast all relevant indexers based on their dimension names (see :ref:`compute.broadcasting` for full details). Index the underling array by the broadcast indexers, using NumPy's advanced indexing rules. If any ...
matlab_dayon 14 Jan 2021 Thank you. I changed the initial conditions so that I would have x(0) = -5, -.4,...,.4, .5, and I wanted my interval for my independent variable to be from 0 to 10. When I used the following code: ...
Hump-day Challenger - MATLAB IndexingThanks to Sean de and Andrew Newell both!didx(skip:skip:end) = prod([RA(1:ii-1),(SA(1:ii)+mpart)])+didx(skip:skip:end);Yes
You can see from the output of whos that the class of the variable D is logical. The logical indexing expression C(D) extracts all the values of C corresponding to nonzero values of D and returns them as a column vector. C(D) ...
