TF = isfield(S,field) returns 1 if field is the name of a field of the structure array S.Otherwise, it returns 0.. If field is an array that contains multiple names and S is a structure array, then TF is a logical array that has the same size.. If S is not a structure array, then isfield returns 0.

Sep 27, 2006 · isfield has been built into MATLAB for a few releases now. We felt it was important to do this after talking to some customers with customers who had struct arrays with a large number (10s of thousands) of fields, and they found the performance too slow.

Check if a group of properties are dynamic properties in the geoshape vector. tf = isfield (gs, { 'Latitude', 'longitude', 'Name' }) tf = 1x3 logical array 0 0 1. The first element of tf is 0 (false) because the property Latitude exists in the geoshape vector but is not a dynamic property. The second element of tf is 0 (false) because the ...

TF = isfield (S,field) returns 1 if field is the name of a field of the structure array S. Otherwise, it returns 0. If field is an array that contains multiple names and S is a structure array, then TF is a logical array that has the same size. If S is not a structure array, then isfield returns 0.

TF = isfield(S,field) 는 field가 구조체형 배열 S의 필드 이름이면 1을 반환합니다.그렇지 않으면, 0을 반환합니다. field가 여러 개의 이름을 포함하는 배열이고 S가 구조체형 배열이면 TF는 동일한 크기를 갖는 논리형 배열입니다.. S가 구조체형 배열이 아니면 isfield는 0을 반환합니다.

TF = isfield( S , field ) returns 1 if field is the name of a field of the structure array S . Otherwise, it returns 0 . If field is an array that contains ...

此 MATLAB 函数 返回 1。否则，将返回 0。 如果 field 是结构体数组 S 的一个字段的名称，则 TF = isfield(S,field) 返回 1。 否则，将返回 0。. 如果 field 是包含多个名称的数组且 S 是结构体数组，则 TF 是大小相同的逻辑数组。. 如果 S 不是结构体数组，则 isfield 返回 0。

TF = isfield(S,field) returns 1 if field is the name of a field of the structure array S.Otherwise, it returns 0.. If field is an array that contains multiple names and S is a structure array, then TF is a logical array that has the same size.. If S is not a structure array, then isfield returns 0.

isfield. Determine if item is a MATLAB structure array field. Syntax. tf = isfield(A,'field') Description. tf = isfield(A,'field') returns logical true (1) if field is the name of a field in the structure array A, and logical false (0) otherwise. Examples. Given the following MATLAB structure,

Check if individual properties are dynamic properties in the mappoint vector. isfield (mp, 'X') ans = logical 0. This result is 0 (false) because property X in the mappoint vector is not a dynamic property. isfield (mp, 'Name') ans = logical 1. This result is 1 (true) because the property Name is a dynamic property that exists in the mappoint ...

The function mtlb_isfield (st,f) is used by mfile2sci to replace isfield (st,f) when it was not possible to know what were the inputs while porting Matlab code to Scilab. This function will determine the correct semantic at run time. If you want to have a more efficient code it is possible to replace mtlb_isfield calls: If st is a structure tf ...

Sep 16, 2013 · There is no MATLAB function that examines every level of a structure of structures, or nested structure, to determine if a field exists. The 'isfield' function examines only the top level of a nested structure. To determine if a field exists at any other level, you can use either of the following methods. 1. To determine if a field exists in a ...
