它使用一个Logical_Array,用“1”表示NaN值,用“0”表示non-NaN值。然后,使用find()的每一行都返回“0”/non-NaN编号的所有索引。通过使用max()计算最大索引,可以为每一行检索最后/最大列。取max允许NaN值分散的情况。 Matrix = [1 2 NaN 4 5; 1 NaN 3 NaN 5; 1 2 NaN NaN NaN]; [Matrix_Height...
siz 是一个包含 ndim(A) 个元素(此示例为 2 个元素)的向量,其中 siz(1) 为行数,siz(2) 为列数。 注意 对于矩阵,[I,J] = ind2sub(size(A),find(A>5)) 与 [I,J] = find(A>5) 返回相同的值。 [I1,I2,I3,...,In] = ind2sub(siz,IND) 返回 n 个下标数组 I1,I2,...,In,其中包...

Open in MATLAB Online here is an example which can give you idea how you can do it: ThemeCopy a = rand(1152, 4); a(randi(1152, 1, 20), :) = NaN; a = num2cell(a); b = cellfun(@isnan, a); idx = find(b(:,1)); for i = 2:size(a, 2) idx = union(...
nan_locations = find(isnan(A)); A(nan_locations) = 0; A = filter2(ones(3,3), A); A(nan_locations) = NaN; Read blog on logical indexing We hope that these examples in the article give you a feel for ways you can express algorithms compactly and efficiently. Including these techni...

Examples of messy, unstructured, and generally ugly programs are plenty, but there are also places where you are almost guaranteed to find well-structured code. Take, for example the MATLAB internals: Many of the functions that you might make use of when programming MATLAB are implemented in MA...
