我已经在线查看并完成了以下操作,将一个.mat文件转换为一个.csv文件,但是我一直看到一个错误。这就是我尝试过的: FileData = load('mydata.mat'); csvwrite('weights.csv', FileData); 然而,我在matlab中一直看到以下错误: Undefined function 'real' for input arguments of type 'struct'. Error in dlmw...
Functions that create arrays (such as Inf, NaN, ones, rand, randi, randn, and zeros) do not support size specifications as input arguments. Instead, the size of the generated array is determined by the size of the input variables to your functions. Enough array elements are generated to sa...
Many MATLAB functions that start withisreturn logical arrays and are very useful for logical indexing. For example, you could replace all the NaN elements in an array with another value by using a combination ofisnan, logical indexing, and scalar expansion with one line of code. B(isnan(B)...
As mentioned above, the default response of the program is to make all arrays the size of the largest dimensions of the arrays given. For example, if you submit a 1x3 array and a 3x1 array, the result will be 3x3 arrays with 2 rows of NaN for the first array and two columns of Na...
需要说明的是没有办法精确计算程序执行时间,matlab帮助这样写到“Keep in mind that tic and toc measure overall elapsed time. Make sure that no other applications are running in the background on your system that could affect the timing of your MATLAB programs.”意思是说在程序执行的背后很可能有...
A mistake that beginners tend to make is to define mask as an array of integers, such as mask = zeros(n,1);. ↩ Remember: You can combine several masks with the logical operators & (and) and | (or). For example, mask = isnan(v) | isinf(v); is true wherever v!has a NaN...
