I am getting this errors:
Error using griddedInterpolant. The grid vectors must contain unique points.
Error in interp1 (line 161)
F =griddedInterpolant(X,V,method)
Error in interpolation_diff (line 184)
ai_b = interp1(b(:,1), b(:,2),0:4095);
My code line is:
[r,c] = size(b);
ai_b = interp1(b(:,1), b(:,2),0:4095);

x = b(:,1) ;
y = b(:,2) ;
xi = linspace(min(x),max(x),4095)' ;
ai_b = interp1(x,y,xi);

Thanks for the response.
It is showing an error as ' the input must be scalar for linspace '

Actually I have used same code for another material as well but for both I have loaded different mat files and then wrote the above stated code accordingly.
But it is showing error as:
Error using griddedInterpolant. The grid vectors must contain unique points.
