Table shows 1x1 sym

Hi every body,

I have a simple function to solve an equation using some date from a table:

function [s] = angle(r2,a2)
syms a1

x=a2*pi/180;

s=(vpasolve(sin(pi-a1)==(r2/0.8)*sin(a1-x),a1))*180/3.14
end

Command Window:

>> r2=[3.89;3.90;3.91]
r2 =
    3.8900
    3.9000
    3.9100
>> a2=[8.87;8.86;8.83]
a2 =
    8.8700
    8.8600
    8.8300
>> param=table(r2,a2)
param =
  3×2 table
     r2      a2 
    ____    ____

    3.89    8.87
     3.9    8.86
    3.91    8.83
>> stats = rowfun(@angle,param,'OutputVariableNames', {'simulatedMean'  })
 s =
 11.154670370349323645591725425313
 s =
 11.134816655884783149835261112257
 s =
 11.089983811612564656965216573319
 stats =
  3×1 table
    simulatedMean
    _____________

      [1×1 sym]  
      [1×1 sym]  
      [1×1 sym]  

Every thing is o.k but I have the answers in the table stats in form of 1x1 sym. They should be the values of s= 11.15 , 11.13 , 11.08

Could you please help me. I really appreciate that.

function s = angle(r2,a2)

Change the return value in function to s

Thanks for your reply. I did it but still have the problem.

r2=[3.89;3.90;3.91]

r2 = 3×1

3.8900 3.9000 3.9100

a2=[8.87;8.86;8.83]

a2 = 3×1

8.8700 8.8600 8.8300

param=table(r2,a2)

param = 3×2 table
     r2      a2 
    ____    ____

    3.89    8.87
     3.9    8.86
    3.91    8.83

stats = rowfun(@angle,param,'OutputVariableNames', {'simulatedMean'})

s = 

11.154670370349323645591725425313

s = 

11.134816655884783149835261112257

s = 

11.089983811612564656965216573319

stats = 3×1 table
              simulatedMean

I did 'copy paste' your code exactly but still doesn't work. I don't know why.

[Torsten]

If you add the line

s = double(s)

in function "angle", what do you get ?

[Navid karimi]

Thanks @Torsten now the table shows correctly.
