# Input argument type matlab

nargin returns the number of function input arguments given in the call to the currently executing function. Use this syntax in the body of a function only. Use this syntax in the body of a function only. I would like to ensure that the input arguments to a user-defined MATLAB function (contained in an m-file) are of a certain type. I understand that MATLAB automatically assigns data types to variables (to the liking of some and the dismay of others), but I would like to know if there is an option of "strict data typing" in MATLAB, or something of the sort, especially for input arguments for a. Below is an example of a function in which I would like to specify the input argument data type. It resides in a file called strict_data_type_test.m in MATLAB's current path. In this function, I would like to force the variable yes_or_no to be of MATLAB's logical data type.

Usually this is either . Below is an example of a function in which I would like to specify the input argument data type. It resides in a file called strict_data_type_test.m in MATLAB's current path. In this function, I would like to force the variable yes_or_no to be of MATLAB's logical data type. By default, the data type mode for MATLAB Function block function arguments is. This means that the function argument inherits its data type from the incoming or outgoing signal. To override the default type, you first choose a data type mode and then select a data type based on the mode. Define a function that accepts a variable number of input arguments using varargin. The varargin argument is a cell array that contains the function inputs, where each input is in its own cell.

and enjoyDocumentation Help Center. The arguments block is optional. If you include an arguments block, it must appear before the first executable line of the function. Functions can include multiple arguments blocks. Each argument can have one or more restrictions or a default value, as shown in this syntax:. A colon allows any length in that dimension. The dimensions of the input must match dimensions exactly or be compatible with the size specified by dimensions. For example, 1,: specifies the input must be a 1-by- n row vector, but an n -by-1 column vector is compatible.
