2D MIMO virtual antenna array with different tx and rx antennas
Hi All!
I am trying to build up an antenna object, which consists of 3 TX and 4 RX antennas, which would eventually end up as a 2D 12 element virtual antenna array. The TX and RX antennas would have different design, therefore I need to import different characteristics for TX and RX.
My plan is to check and optimize the virtual antenna array pattern, however, I cannot combine the TX and RX array as a virtual array.
I can also combine the TX and RX patterns, but as far as I know, that is just the magnitude, and not the phase. I want to make sure, that the TX and RX phase pattern is properly taken into account.
Here is the code I have so far (the antennas are not real, just a simulated patch and vivaldi antenna data, I won’t even use vivaldi antenna in the future). All the filepath and sensor positions info is deleted.
Many thanks in advance!

Help needed to make a 3d contour plot
Hello. I have around 50K data points (x,y,z co-ordinates of each point) and the value of a function at each of these points. I want to make a filled contour plot of this function on the 3d surface that would so be formed by joining all the data points. I have tried various functions like contour3, tricontour, scatter3, surf etc but nothing seems to work. If it matters, the value of the function is in no way dependent on the co-ordinates of the point.

How can I add dates to bar charts when the data I am plotting are matrices?
I am trying to plot a matrix of N * 7 elements in a bar chart.
N are different dates for which I have 7 variables under study. If I have N around 8, the graph looks nice and it shows what I want. Namely, the date for the group of variables on the x axis. However, if I have N = 20 or bigger it only shows the first five dates spanning the whole x-axis.
The code I am using right now is the following:
width = 6; % Width in inches
height = 3; % Height in inches
%FIGURE 1: Sectors Jump Days
fig1=figure(1);
pos = get(gcf, ‘Position’);
set(gcf, ‘Position’, [pos(1) pos(2) width*100, height*100])

set(gca,’XTickLabel’,dayIndjumpStr)

How do I add the COVID-19 recession to the graph?
Thank you,
Mpho Dear Experts,
I am having a challenge with recessionplot. I have plotted this monthly time series data (1971M1-2021M10) and clicked ‘recessionplot’.
However, the recessionplot algorithm does not shade (grey) the COVID-19 recession (2020M02-2020M04).
How do I add the COVID-19 recession to the graph?
Thank you,

Get properties from Aspen Plus
Hello Matlab community,
I want to use material properties from Aspen Properties V9 to calculate some dimensionless numbers. For example I want to get out the heat capacity, thermal heat conductivity, etc. of water at different temperatures and pressures. Is this possible?

I need help validating my forward kinematic using Simulink and the Robotic Systems Toolbox for a surgical robot.
Hi all,
I am a student and I am working on a surgical eye robot which utilises a remote centre of motion mechanism (RCM). I have found the forward kinematics for it using the DH method and another method. I have also found the Jacobian velocity matrix for it. However, my Jacobian seems a bit off and I am looking to validate it and the forward kinematic using RST. I have exported the CAD model as XML and created an slx file for it. The robot composes of multiple joints. However, in reality, only 4 joints are actuation joints, the rest are closed loop joints that reduce the robots DOF to 1 or 2 DOF (pitch and translation).
I have set up the robots and actuated it fine using a constant block connected a degree to radians block which is then connected to the robot, which is connected to a MATLAB function script which is then connected to a display to show me the homogenous matrix.
I am now at the stage where I am looking to connect a GetTransform block in order to retrieve the forward kinematic. Below is the way I am connecting the blocks. My apologies since I am using a different computer and can’t screenshot my layout.
3 Sine blocks and a constant block connected to the robots (I have made the robots connection and blocks a subsystem). From the robot subsystem, it’s connected to a mux that takes 4 inputs. The mux is connected to the GetTransform block. The GetTransform block is connected to a Coordinate Transformation Conversion block which is then connected to a scope.
All of my setup seems fine. However, I am getting an error that says the input is a vector of 4 whereas the outputs requires 11. I know this is due to the joints block where I have set up 4 of them to sense the postion and computed the torque automatically and I have 11 joints in total. When I add an additional Simulink to PS and PS to simulink to another joint, I get an error like this: "The input is a vector of 5 whereas the outputs requires 11". As mentioned, only 4 of the joints are actuating joints and joints that I need to find the forward kinematic for. How can I fix this issue without adding more joints to sense the position?
My second question is rather simple. I am using 3R1P configuration. I know I can get a constant block connected to a degrees to radians block to control the revolute arm of the robot. What is a similar setup I can use to move the prismatic joints?
Thank you so much for the help in advance!Hi all,
