Your function returns the variable‘value’, however you never assign anything to‘value’in your function (at least not that I can see). It seems that you want to return‘T’or‘TL’. Consider assigning one of them to‘value’.
the function return value "nframe" might be unset.错误信息，函数返回值nframe未被定义 前面两个是警告，不影响程序运行（但警告信息通常也可能是潜在的错误），真正影响程序运行的是第三个。注意在函数体中给返回参数nframe赋值——如果有条件语句，要确保在每一条可能的执行路径该变量都能被赋值。
% In this case, F = humps(X) returns the scalar function value F of % the HUMPS function evaluated at X. % % FUN can also be an anonymous function: % X = fmincon(@(x) 3*sin(x(1))+exp(x(2)),[1;1],[],[],[],[],[0 0]) % returns X = [0;0]. % % If FUN or...

The prod function supports GPU array input with these usage notes and limitations: 64-bit integers are not supported with the "native" option. The order of the products in prod operation is not defined. Therefore, the prod operation on a GPU array might not return exactly the same answer as...
