MATLAB: Making a table for degrees and radians

arraysMATLABtable

Hi,

I'm trying to make a table off of two arrays but on using the 'table' function, I'm only getting the size of the arrays.

clc;
clear all;
Degrees=[0,10,20,30,40,50,60,70,80,90,100,110,120,130,140,150,160,170,180,190,200,210,220,230,240,250,260,270,280,290,300,310,320,330,340,350,360];
%for i=1:length(Degrees)
 %   Radians(i)=Degrees(i)*(pi/180);
%end
T=table(Degrees);
T.Radians=(T.Degrees*pi)./180;
T(1:1,:)

How do I make the table display the values of the arrays Degrees and Radians?

TABLE = array2table([Degrees(:), deg2rad(Degrees(:))], 'VariableNames', {'DEGREES', 'RADIANS'})

MATLAB: Scale any angle between [0, 180] and [0,-181] degrees

Andrew - suppose you have your angle whether it is 750 or 950. So long as the angle is greater than 180 degrees, then just subtract 360 from it. This will ensure that your "scaled" angle is in the interval [-179, 180] degrees. For example,

 angle = 750;
 while angle > 180
       angle = angle - 360;
 end

The above will give you the "scaled" angle of 30 degrees. Replace with 950 and the answer will be -130.

MATLAB: How separate data from a table and convert every column in vector if this seáration depends on the label ‘D’ or ‘E’

Try this:

C = { 111          90          50        'D'
      321          80          50        'E'
      121          70          50        'E'
      222          70          50        'D'
      333          80          50        'D'};                              % Copy-Paste Data
T = cell2table(C, 'VariableNames',{'angle1','angle2','angle3','label'});    % Create Table
G = findgroups(T{:,4});                                                     % Could Also Use ‘unique’
Angles = accumarray(G, (1:numel(G)).',[], @(x){T(x,:)});                    % Group Data Into Separate Tables

then defining:

AnglesD = Angles{1}
AnglesE = Angles{2}

produces:

AnglesD =
  3×4 table
    angle1    angle2    angle3    label
    ______    ______    ______    _____
     111        90        50      {'D'}
     222        70        50      {'D'}
     333        80        50      {'D'}
AnglesE =
  2×4 table
    angle1    angle2    angle3    label
    ______    ______    ______    _____
     321        80        50      {'E'}
     121        70        50      {'E'}

To extract them from the tables:

Angle1D = AnglesD.angle1.'
Angle1E = AnglesE.angle1.'

producing:

Angle1D =
   111   222   333
Angle1E =
   321   121

and similarly for the others.
