PyErr_SetString(PyExc_TypeError, "Expected an array of doubles"); PyBuffer_Release(&view); return NULL; } 一旦我们已经确定了底层的缓存区信息,那只需要简单的将它传给C函数,然后会被当做是一个普通的C数组了。 实际上,我们不必担心是怎样的数组类型或者它是被什么库创建出来的。 这也是为什么这个函数能...

因此可以直接传递数据类型并使用它来分配数组。一些覆盖使矩阵更易于操作和显示。

The unit tests load the variablepositionfromposition.matand passpositiontocallKalmanFilter. Therefore, the input tocallKalmanFiltermust have the properties thatpositionhas. In the MATLAB workspace, if you loadposition.mat, you see thatpositionis a 2-by-310 array of doubles. ...
In C, it is more efficient to find the starting address of the array and then use pointer autoincrementing to access successive elements. For example, to find the starting address of a numerical array, call one of the typed data access functions, for example,mxGetDoublesormxGetComplexDoubles...
