May 30, 2018 · Im im trying to validate my engineering work using Matlab. I have a series of x and y data that I have plotted on a Log-Log Graph. The result is a curve. What I need to do is to apply a curve f...

Apr 14, 2017 · ln(x) = log 10 (x)/log 10 (e) so, just write that code in matlab. my_ln= log 10 ( number ) / log 10 ( exp(1) ); you can also make it as a function and call it whenever you need it, function [val] = ln_fun(number) val = log 10 (number)/ log 10 ( exp(1) ); end *remember the log general formula → log base (number)

Apr 8, 2016 · I want the function to have log scale at the same time the X labels have values of X which are [1 2 4 8 16 32 64]. I want also to make circle around the values that are intersected with X, Y, and Z because if you can see from X values isn't corresponding to values in the graph

Jan 21, 2019 · ...but your function handle only accepts 2 inputs => MATLAB is trying to pass 4 inputs into a function that only accepts 2 => Error: Too many input arguments.. What you should probably do is define a proper function which has 4 inputs and 1 or 2 outputs, then refer to it using @funcName when calling mle, i.e.:

Jun 5, 2014 · Obviously, I can edit my_function() in the above example so that it can modify the history field. NOTE in response to discussion below: the motivation for doing this is to have the history "attached" to the data in question, rather than say, in a separate log file which would then need to be packaged with the data somehow. Can this be done?

Feb 25, 2015 · provided that d ~= c + x.*wrightOmega(log(-(c-d)./x) - (c-d)./x) (i.e., d ~= c+b-a, x is 0/0 in this case). This is equivalent to the principal branch of the Lambert W function, W 0, which I think is the solution branch you want. Just as with lambertW, there's a wrightOmega function in the Symbolic Math toolbox. Unfortunately, this will ...

May 15, 2021 · You're doing everything right except for the plotting, in the first plot you defined the x-axis to be log(lux) and the y-axis to be log(ohm), but to adhere to that in the second case you need to flip the arguments: plot(log(lfun(t, a, b)), log(t), '--g') t refers to 'ohm' and must therefore be displayed on the y-axis to coincide with the first ...

Feb 17, 2013 · if you don't convert C1 to double, then I will also be of type uint8 - it will not contain what you want and log function will not work with it. Share Improve this answer

Oct 8, 2013 · I have graphed two matrices on a log-log plot and I determined the slope of the line of best fit with the following: loglog(x,y); polyfit(log(width_matrix),log(error_matrix),1) Is it possible to draw the line of best fit on the same log-log plot and perhaps include its equation on the graph?

Apr 12, 2012 · I intend to peform Laplacian of Gaussian edge operator in matlab.. This is the knowledge i have LOG operators are second-order deriatives operator. Second order deriatives operator result in zero-
