How do you make a sinusoidal function in MATLAB?

sine = dsp. SineWave creates a sine wave object that generates a real-valued sinusoid with an amplitude of 1, a frequency of 100 Hz, and a phase offset of 0. By default, the sine wave object generates only one sample. sine = dsp.

How do you smooth a sine wave in MATLAB?

Use the Savitkzy-Golay filter with order 3 or 5. It will smooth it right out. Post your data if you want a demo. As you know, the sine wave can be estimated as a Taylor series so with enough terms and the proper window size in the Savitzky-Golay filter you should be able to get a reasonable sine wave out.

How do you display a sine wave in MATLAB?

in sine function in MATLAB it is always sin(wt). here frequency w is in radian/sec not f (in HZ) so w will give you the no. of the cycle. if you want to use the sin(2*pi*60*t) you can use the sind(2*pi*9.545*t).

How do you give sinusoidal input in Simulink?

On the Sine Wave block dialog box, set Time to Use external signal so that an input port appears on the block icon. Connect a clock signal to this input port using a Digital Clock block. Set the sample time of the clock signal to the sample time of the Sine Wave block.
