example. 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.

The base 10 logarithm is log10(x) , not log(x) . Try using axis tight or axis([xmin xmax ymin ymax]) after the ezplot command.. My graph does not fill the whole  semilogx(Y) creates a plot using a base 10 logarithmic scale for the x-axis and a linear scale for the y-axis. It plots the columns of Y versus their index if Y  217 kB — Andra möjligheter är att rita med olika färger och olika plotsymboler, t ex optionen 'o' för små ringar, i stället för en kurva (se hjälpfunktionen till plot). >> axis([-1 32 -​  160 kB — Detta är en handledning till MATLAB, ursprungligen för version 5, men här åtminstone delvis mod- ifierad för version 6. exp , log( = ln) , log10( = lg) sin , cos , tan , av kommandot axis.

Senare skapas en modell i MATLAB med partiklar som färdas mot det geomagnetiska fältet.

En av de tekniker som beskrivs är Islands of Music (Matlab-kod finns att tillgå): like overlapping regions or strong dependence on the choice of coordinate axes. Notera att värdena på axlarna inte är log10-värden utan de riktiga "oskalade" 

The best way to create that type of axes is to use the semilogy function. Alternatively, you can set the ‘YScale’ property on the axes: set(gca, 'YScale' , 'log' ) View MATLAB Command. Create a log-linear plot containing two lines, and return the line objects in the variable slg.

– Jack Reacher Nov 23 '16 at 2:57 Concerning the validity of your graphs: if you use a simple loudspeaker-microphone setting for your measurements, most of the peaks and valeys are typically determined by your loudspeaker instead of your SM57. I have an assignment in Matlab and one of the instructions in the assignments is to not use "user-defined functions", I don't actually know what that is and I tried to understand it but couldn't, so can someone tell me if my small code has any user-defined functions. works fine. I can change the color scale, axes ranges, and everything through the menus from the created image. However, transforming the image so it displays a log Y axis does nothing to the image. Pixels are still squares of equal size (I think that is the key around my issue).

If you want the text to reflect the order of magnitude of the axis limits, you may need to do some of the log10 processing demonstrated above first. 2020-01-06 multiple logarithmic x-axes. Learn more about multiple axes, logarithmic axis how to plot both axis (X and Y axis) as log Learn more about log scale on axis L = logm(A) is the principal matrix logarithm of A, the inverse of expm(A).The output, L, is the unique logarithm for which every eigenvalue has imaginary part lying strictly between –π and π.If A is singular or has any eigenvalues on the negative real axis, then the principal logarithm is undefined.

For complex and negative real values of X, the log10 function returns complex values. 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? example. Y = log10 (X) returns the common logarithm of each element in array X .

Can I change the axes in a way that I will see 10^(~something~) in both axes?
