I have to find the values for x when y=0 but i cant seem to make it work. I have tried with interp1 but it seems that it gives me an answer of x=2.3490 which is clearly wrong,since there are 2 points in the plot where y=0. Here's the code:
x = [0:0.001:pi]f = exp(x/4).*sin(x)-1;plot(x,f)xlabel('Axis x');ylabel('Axis y');newLim = get(gca,'XLim'); newx = linspace(newLim(1), newLim(2), 30); set(gca,'XTick', newx);% what I tried:
yi = 0 ;xi = interp1(f,x,yi) ;hold onsemilogy(xi,yi,'*r')
