MATLAB: ‘double’ input argument not found using a function

doublefindpeaksint16

Hello,

I have got a int16 array (called allAudio) and would like to run the function 'findpeaks' on it. When I write pks = findpeaks(allAudio(1,:)), the error message says: "Error using findpeaks (line 59) Input arguments must be 'double'."

 I don't understand it... Any thoughts?

findpeaks only operates on numbers that are 64 bit floating point numbers (they're called doubles).

Convert your 16bit integers to double with the function "double".

double_allAudio = double(allAudio);

MATLAB: Finding local minima and maxima

You already found the correct functions. Applying them appropriately appears to be the problem.

Try this:

t = (0:100)*0.6*10^-3;
x1 = 3*sin(2*pi*100*t);
TFmax = islocalmax(x1);
TFmin = islocalmin(x1);
figure
plot(t, x1)
hold on
plot(t(TFmax), x1(TFmax), '^r', 'MarkerFaceColor','r')
plot(t(TFmin), x1(TFmin), 'vg', 'MarkerFaceColor','g')
hold off
grid
