Liksom de flesta programpaket uppgraderas Maple relativt ofta.

In terms of power, the dB increase is 10*log10(V2^2/V1^2) = 6 dB. It's always … Right now MATLAB either omits the last label if XTickLabelModel is 'auto' or can display strings of the type '10^X' or can show only numbers as decimals (i.e. '0.1, 1, 10, 0.1'). Is there a way to control directly the format of axis tick labels, or I have to work it around using a … MATLAB: LOG vs LOG10 plot. I want to have a plot in a 'log10(x)log10(y)' scale. Up to now, I was using the 'loglog' plot. Is the 'loglog' plot actually a lnx-lny plot?

XTickLabels = num2str(10^-1, 10^0, 10^1, 10^-1]. But now I would like to use a log axis for the frequency axis since my signal covers many decades in frequency content. I realize the I can just form 'log10(f)' and plot it as a linear axis but this is difficult to interpret when analyzing the plot (e.g. what is the freq if log10(f)=0.4 ?) Is there anyway to get a genuine log axis (1, 10 100, 1000) 1、log10函数：求以10为底的对数2、用法说明 y = log10(x) 函数对数组x的元素逐个进行以10为底的对数运算。y = a+b*i，有log10(y) = log10(abs(y))+i*atan2(b,a)3、举例说明>> x = 20x = 20>> y = log10(x)y = 1.3010>> x When you choose "log" as the scale for an axis, Matlab either chooses to use log10(x) or -log10(-x) as the transform, depending on whether your data is in the positive or negative domain. As you've found, you can't have both at the same time because both halves map data into the [-inf inf] space.
