Matlab eval

Help Center Help Center. Although the eval function is very powerful and flexible, it is not always the best solution to a programming problem. Code that calls eval is often less efficient and more difficult to read and debug than code that uses other functions or language constructs. For example:. However, because code in an eval statement can change at run time, it is not compiled. Code within an eval statement can unexpectedly create or assign to a variable already in the current workspace, overwriting existing data. Concatenated character vectors within an eval statement are often difficult to read. Other language constructs can simplify the syntax in your code. For many common uses of eval , there are preferred alternate approaches, as shown in the following examples. A frequent use of the eval function is to create sets of variables such as A1 , A2 , The preferred method is to store related data in a single array. If the data sets are of different types or sizes, use a structure or cell array. For example, create a cell array that contains 10 elements, where each element is a numeric array:.
