I want to change that value from a "NaN" to any other real number. At present, my code この MATLAB 関数は、A の要素が NaN の位置に 1 (true) を含み、要素がそれ以外である位置に 0 (false) を含む logical 配列を返します。 I find myself writing stuff like this a lot: if isnumeric(X) & ~isnan(X) % etc etc end Before I clutter the namespace with my own test function out = isanumber(X) out = isnumeric(X) &a Undefined function or variable 'isnan'. isnan Detect NaN elements of an array Syntax TF = isnan(A) Description TF = isnan(A) returns an array the same size as A containing logical true (1) where the elements of A are NaN s and logical false (0) By the way, IF statements in MATLAB pass the conditional if ALL of the elements evaluate to true. For any real A, exactly one of the three quantities Diese MATLAB-Funktion gibt ein logisches Array zurück, das 1 (true) enthält, wo die Elemente von A NaN sind, anderenfalls enthält es 0 (false). Learn how to use isnan with examples, syntax, and tips for symbolic expressions and For a complex number z, isnan(z) returns 1 if either the real or imaginary part of z is NaN, and 0 if both the real and imaginary parts are finite or Inf. If it does, then I don't want my action to be performed. Sorry for not being precise but here A is a matrix with A (i+2,11) denoting the value at (i+2)th row and 11th column. Questa funzione MATLAB restituisce un array logico contenente 1 (true) dove gli elementi di A sono NaN e 0 (false) dove non lo sono. La funzione 'isnan' in MATLAB restituisce un array logico che identifica gli elementi NaN nell'array originale. If it contains no NaNs, the action should be performed. As you have it, that IF statement would never pass, no matter what 'i' is, because 11 I am testing a vector to see whether it contains any NaNs. 'isnan' sta per 'non è un numero' e la funzione restituirà 1 (vero) per ogni TF = isnan (A) returns an array the same size as A containing logical true (1) where the elements of A are NaN s and logical false (0) where they are not. This MATLAB function returns an array of the same size as A containing logical 1s (true) where the elements of A are symbolic NaNs, and logical 0s (false) where they are not. This MATLAB function returns a logical array containing 1 (true) where the elements of A are NaN, and 0 (false) where they are not. Learn more about isnan, error MATLAB This MATLAB function returns a logical array containing 1 (true) where the elements of A are NaN, and 0 (false) where they are not. Are you wanting to check whether i+2 or 11 is a nan? Well we know that 11 is not a nan, so let's leave that out. Thus we only have to check on 'i'. This MATLAB function returns a boolean indicating whether a fixed. Learn the syntax, description, examples, and related functions of isnan. Explore definitions, usage, and practical examples in our concise guide. isnan(A) returns a logical array indicating whether the elements of A are NaN (not a number). If 'i' is not a nan then i+2 is not a nan. All MATLAB numeric classes, logical, char, duration, or calendarDuration All MATLAB classes that overload anynan or isnan. Interval object A is NaN. Now is 'i' the Always use the isnan function to verify that the elements in an array are NaN: MATLAB preserves the “Not a Number” status of alternate NaN representations and treats all of the different representations isnan Detect NaN elements of an array Syntax TF = isnan(A) Description TF = isnan(A) returns an array the same size as A containing logical true (1) where the elements of A are NaN s and logical false (0) Discover the nan meaning in matlab and unlock the mysteries of missing values. k = isnumeric (A) returns logical true (1) if A is a isnan(A) returns a logical array of the same size as A, where 1 indicates a symbolic NaN and 0 indicates otherwise.
