I have particle size data for differrent De(parameter) values.
I have plotted 2Dbar graphs, I want stack all figures into one 3D figure window.
I stacked everything, that looks like the image below

But I want to rotate axis in such a way that: Particle_density(Y-axis) in vertical, Particle size(X-axis) in horizontal and De (z-axis) per pendicular to the screen. It should look like this image below

I have attached my matlab code to this thread.
Please guide me, how to do this. Thanks in advanceI have particle size data for differrent De(parameter) values.

Hi guys, i have to make a triangulation 3D of a solid of which i have the coordinates (x,y,z) of 20ooo points and i need to export the result (so the tetrahedra) to an stl file.
How can I use properly the stlwrite function, in particular the option indicated with TRIANGULATION?

I have two axes (top, bottom) in a GUI. I do not want the x-axis of the top ghraph to be present (because it is the same as the bottom x-axis). I could not find how to handle separately the x and y axis visibility.

Hey community, I have two variables with <10 x 1> double data. I am to plot these two in a plot, but would like to have the axes to be intersecting each other in origin (0,0). Instead in the axes are shown with intersecting at for example (-2000,-6), my lowest x-value is -1200, lowest y-value is -6. Here it would be great to have the x-axis through y=0, so that differences from y=0 easily can be seen graphically.

How would I do that, is there a command you could use in the script written, to make it move the axes? I have a large script to evaluate a lot of graphs in, so a MATLAB-command would be preferable to a tool in the figure builder.

The (simple) code used is as following:

%% person5 – Puls
hold on
plot(person5_ethanol_ekgpuls_tid,person5_ethanol_ekgpuls,’g.-‘)
xlabel(‘Tid/Sek’)
ylabel(‘Blodtryk/MmHg’)
title(‘Forsøgsperson #5 Ethanol Ekg Puls’)

Hope that my question is understandable and that it can be done.Hey community, I have two variables with <10 x 1> double data.

I am reading a big CSV file (500K lines) with readtable. In the CSV, some columns have the first 250+ lines empty (e.g. ",,,," in the CSV), while the non-missing values below (pretty rare) are either text strings or dates (in the DD-MM-YYYY format). Readtable() somehow interprets these columns as numeric, and so converts all the strings and dates into NaNs – thus, I end up with 100% NaN-filled columns instead of rarely-populated data (among empty strings and NaTs).
Furthermore, if I move the "with-data" lines up – even a few dozens positions up – readtable() starts to read everything normally!
So, it looks like readtable() checks only ~250 first values to determine the type of the column, which, in my opinion, is a bug! (Although I understand that it was likely made to improve speed.)

Is there a way to fix it systematically? I have lots of such CSVs with thousands of columns in them – so, a manual check and manual fix is not an option…

UPD: a test-file (truncated to 510 lines) is attached – the behaviour is still the same. The problem columns are the 2nd and the 3rd (p190, p191). The first non-empty value is on data-line 270.I am reading a big CSV file (500K lines) with readtable.

Dear all,
I am recently trying to use the WLAN examples of the wireless HDL toolbox:
https://jp.mathworks.com/help/wireless-hdl/ug/wlanhdltransmitter.html
https://jp.mathworks.com/help/wireless-hdl/ug/wlanhdlreceiver.html
In these two examples of transmitter and receiver, it seems to support 802.11a/n/ac.
For instance, I would like to use 802.11n, then these should be selected:
HT: switched by "frameFormat"?
ODFM only: How to select?
MCS: which one should be select?
For 20 MHz channel bandwidth, which clock rare should be used in FPGA to drive the HDL codes?
ADC bit width: It seems to be 32 bit by default. How can I change to other bit width?
If I would like to use other than a/n/ac, how can I do?
For such kinds of the configurations or so, I would appreciate if anyone can instruct me how to change them before generating HDL.
Thank you in advance.Dear all,
