Help Center Help Center. When invoked without output arguments, size sys returns a description of type and the input-output dimensions of sys. If sys is a model array, the array size is also described. For identified models, the number of free parameters is also displayed. The lengths of the array dimensions are also included in the response to size when sys is a model array.

Help Center Help Center. For example, for a scalar size m :. If A is a vector, then resize A,m pads or trims A to length m. If A is a matrix, table, or timetable, then resize A,m pads or trims A to have m rows. If A is a multidimensional array, then resize A,m pads or trims A to the size specified by m along the first dimension whose size is greater than 1. Create a four-element column vector, and resize the vector to six elements. By default, the resize function adds zeros to the trailing side of the numeric vector. Resize the vector to two elements. By default, resize removes elements from the trailing side. Resize the first and third vectors to match the length of the second vector.
