Hello, i have imported 2D data from the attached CSV as x_data and y_data.
i have used interp1 function as shown bellow to interpolated my descrete samples into continues function as shown in the code bellow.
Matlab gave me "The grid vectors must contain unique points." error.
I have tried to solve it using 'unique' function as shown bellow but its not working,
Where did i go wrong?
[x, index] = unique(x);
coef_fun = @(xq) interp1(x_data, y_data(index), xq);
xq = linspace(3.5,23,100000);
