Unfortunately, some of the MATLAB functions used by the Curve Fitting Toolbox's fit function are not currently implemented for distributed arrays. In the interim, if you need a simple linear fit to data you might check if polyfit has the functionality you need. I tried some simple examples a...
I am stuck at the beginning with the matrix so i cant get started on the rest of this project. and how do i refer to a line in the matrix so i can calculate that average and all that other stuff? any help at all would be great, thanks ...

There is no way to reshape a 2 * 2 matrix to a 2 * 4 matrix. So output the original matrix. Note: The height and width of the given matrix is in range [1, 100]. The given r and c are all positive. 思路:本题的意思是将一个m*n维数组转换成l*c维,难点在于遍历嵌套vector元素、...
mxArray *yy = mxCreateDoubleMatrix(1,N, mxREAL); //同上。 memcpy(mxGetPr(xx), x, N*sizeof(double)); //将数组x复制到mxarray数组xx中。 memcpy(mxGetPr(yy), y, N*sizeof(double)); //将数组x复制到mxarray数组yy中。 engPutVariable(ep, "xx",xx); //将mxArray数组xx写入到Matlab工作空...
This conversion could be accomplished using CELLFUN in MATLAB. Matrices in MATLAB are however composed of uniform datatype and hence all the cell contents need to be converted to the same data-type.
