Learn more about fft, signal processing, digital signal processing, scaling, scale MATLAB Y = log10(X) returns the common logarithm of each element in array X.The function accepts both real and complex inputs. For real values of X in the interval (0, Inf), log10 returns real values in the interval (-Inf,Inf).For complex and negative real values of X, the log10 function returns complex values. Format axes Tick Labels in log scale. Dear all, an annoying issue when plotting on log scales, is apparently not being able to control the format of axis tick labels. I want to manually set my own labels, e.g.

log10(x) ger 10-logaritmen av x, dvs lg x. axis ger användaren möjlighet att välja skalning på axlarna. I exempelvis Jönsson, kap 5, står mer att läsa om plottning och grafik. 1Punkten här är viktig, eftersom MatLab tolkar x som en lista och x.

h = pcolor(x,y,log10(image_spectrogram(1:floor(Fs/2),:)+1)); h.EdgeColor = 'none' ; What pcolor is doing is actually creating a surface object and setting the view so that you're looking down from the top.

kindly help me I will be highly thankful to you Hi again. If the 20*log10 is not included, what would be the y-axis units please?

If you want negative values to be displayed where the corresponding positive value would be displayed, then plot with abs(y) instead of y. Remember, when you use log, there is an infinite distance in log scale between y = 1 and y = 0, since it has to pass through y = exp(-1), y = exp(-2), y = exp(-3), and so on, each of which needs to be allocated the same screen distance as between y = exp(0

To plot a set of coordinates connected by line segments, specify X and Y as vectors of the same length. Use your actual data as labels, but scale the plotted data with log10. % data x = -3:0.1:3; y = sign(x).*10.^abs(x); % scaling function scale = @(x) sign(x).*log10(abs(x)); N = 7; % number of ticks desired % picking of adequate values for the labels TickMask = linspace(1,numel(y),N); YTickLabels = y(TickMask); % scale labels and plotdata, remove NaN ->inconsistency, do you really want that? Y = log10(X) returns the common logarithm of each element in array X. The function accepts both real and complex inputs.

Remember, when you use log, there is an infinite distance in log scale between y = 1 and y = 0, since it has to pass through y = exp(-1), y = exp(-2), y = exp(-3), and so on, each of which needs to be allocated the same screen distance as between y = exp(0) and y = exp(1) . Log scale on both axes.

Hi again. If the 20*log10 is not included, what would be the y-axis units please? The equation for decibels is A = 10*log10(P2/P1).
