WebNov 25, 2016 · Answers (2) fixpt_interp1 is the Fixed Point Toolbox equivalent of interp1, to be used when the inputs are Fixed Point numbers. From my point of view after read documentation about both is that interp1 only interpolates. fixpt_interp1 offers you the possibility of round the result to fixed point and also scale the inputs.

WebFixed-Point Data in MATLAB. To assign a fixed-point data type to a number or variable in MATLAB, use the fi (Fixed-Point Designer) constructor. The resulting fixed-point value is called a fi object. For example, the following creates fi objects a and b with attributes shown in the display, all of which we can specify when the variables are constructed. Note that … WebInsulate the unsupported function with a cast to double at the input, and a cast back to a fixed-point type at the output. You can then continue converting your code to fixed point, and return to the unsupported function when you have a suitable replacement (Table 2).
