You depend on measurements to make key decisions and discoveries. C Matrix API String Handling Functions How MATLAB Represents Strings in MEX Files. The Sine Wave block only outputs double-precision data types, so to generate a sine wave with a data type of single, you must perform a data type conversion. For example, if the block multiplies an input of type int8 by a gain of int16 and Unconstrained integer sizes is specified, the output data type is sfix24. To convert between types you simply use the type name as a function. If the parameter is set to Microprocessor, Simulink chooses the smallest available hardware data type capable of meeting the range and precision constraints. If you want the resulting array to be interpreted properly as image data, rescale or offset the data when you convert it. If the input port value exceeds the maximum value of the output port's type, it is truncated to that maximum value.
