WebJan 1, 2013 · This is tricking matlab into thinking there are multiple plotting elements (since the second input is a matrix). The documentation states that 'bar' will draw a bar for each column . It just so happens that all but one element of the columns are set to zero, yielding bars that are not visible. WebDescription example TF = isnan (A) returns a logical array containing 1 ( true) where the elements of A are NaN, and 0 ( false) where they are not. If A contains complex numbers, isnan (A) contains 1 for elements with either real or imaginary part is NaN, and 0 for elements where both real and imaginary parts are not NaN. Examples collapse all

WebAug 3, 2024 · So I would like to define: h = @ (x)isnan (f (x)).*f (x)+isnan (f (x)).*g (x) However, when I substitute h (1001), it gives nan. Is it possible to define h so that it gives g (1001) instead of nan? The only restriction is that I need to have anonymous function h for later use, say I would like to use it in integration, i.e., integral (h,0,inf). WebNaN values in a vector are treated as different unique elements. For example, unique ( [1 1 NaN NaN]) returns the row vector [1 NaN NaN]. Use the isnan or ismissing function to detect NaN values in an array. Use the anynan or anymissing function to determine if any array element is NaN.
