showing the error' ??? Object belongs to an incompatible Java class. Error in ==> try2 at 7 set(t,'Data', eg1);'

i was trying to get an matrix out put in matlab7.5 using the prog

eg=[1 2 3 4] %[m,n]= size(eg);

f = figure('Position', [100 100 752 350]); t = uitable('Parent', f, 'Position', [100 100 700 200]); eg1= num2cell(eg); set(t,'Data', eg1);

it is showing the error ??? Object belongs to an incompatible Java class.

Error in ==> try2 at 7 set(t,'Data', eg1); but it showing every matrix of order m*n, but showing the error in case of matrix of order 1*n or m*1. please help me so that i can get the matrix of order m*1. thank you in advanced.

I'm not sure if UITABLE was documented/supported fully in MATLAB 7.5 - I am able to run your code without any errors on MATLAB 7.12 (R2011a).

For MATLAB 7.5, you could try converting your data to a Java object array and then set it on the uitable's Data:

egJ = javaArray('java.lang.Object', 1,4) ;
for m = 1:length(eg)
egJ(1,m) = java.lang.Double(eg(m));
end
set(t, 'Data', egJ);

if UITABLE is not supported in matlab then why it is showing results for any m*n matrix excluding 1*n or m*1 matrix???

please reply

"unsupported" can mean that it exists but is not promised to work for any given case. You got lucky that it worked at all for you.
