MATLAB Online에서 열기 Hi If I want to change all NaNs in an array A to zero, the following works: A(isnan(A))=1000 As far as I see the isnan(A) returns nothing but an array of 1's and 0's. But if I do the following: ...
Find the modulus, mod(A,2), and convert it to a logical array for indexing. Get L = logical(mod(A,2)) L = 3x3 logical array 1 1 0 1 0 1 0 1 1 The array has logical 1 (true) values where A is odd. Use L as a logical index to pick out the odd elements of A. ...

One of my favorite aspects of MATLAB for image processing is how I can use a binary image to index directly into a grayscale image. The technique is calledlogical indexing, and I'm going to show you how it works today. Note: this is an update of a post I originally wrote in2008. L...

"logical subscript contains nas"是一个常见的错误信息,特别是在使用像MATLAB、R或Python等编程语言进行数据处理时。这个错误表明在尝试使用逻辑索引(logical indexing)来访问数组或矩阵的元素时,索引数组中包含了一个或多个非数值(Not a Number,简称NaN)值。由于NaN在逻辑运算中被视为不确定或未定义的值,因此它不...
Assigning a single value to cell array with logical indexing.is questionable, since it may hide mistakes in the logic. Whether or not all the greater and lesser than are correct a string will be assigned to AmpLimitField. It is better that a mistake show up as an empty cell.
where w1, ..., w10 are symbolic real variables. I would like to generate a "binary" array which identifies where the symbolic variables w1, ..., w10 are located, meaning that the output should be A_bin = [0 0 0 1 0 0;
