I have an array (10 rows,10 columns,5 bands) and wonder how I can convert the zero values to NaN. I used the following command line but it's not working. If I replace zero values with another value (like 2) it works but for an odd reason is not working with NaN. A(A==0)=...
MATLAB represents values that are not real or complex numbers with a special value calledNaN, which stands for “Not a Number”. Expressions like0/0andinf/infresult inNaN, as do any arithmetic operations involving aNaN: x = 0/0 x = NaN You can also createNaNs by: x = NaN; whos x ...
% Create sample numeric arrays of year values Y and day values D. In this case, the month value M is a scalar. Y = [2014;2013;2012]; M = 01; D = [31;30;31]; % Create the datetime array. t = datetime(Y,M,D) % Specify a custom display format for the output, using the ...

Matlab抛出的异常说明str2num函数使用错误,参数必须是字符数组(char array)或者是字符串(string)。在后台看了下获得的listbox里面的数据如下: list_string = ' 56 30 3.09 0' ' 32 46 3.83 30' ' 19 48 3.91 76' ……(省略一大堆数据) ' 31 301 9.79 6634' ...
repmat是将矩阵按要求扩增。repmat([1:N]',[1,2]))：就是将[1:N]'看成一个整体，就相当于一个元素，将这个大的“元素”扩增为1x2的矩阵，如果p是整数，则就是将1x2矩阵p倍输出，即三维扩增。以下是Matlab的help结果：REPMAT Replicate and tile an array.B = repmat(A,M,N)creates a ...
