Producing a Java-formated matrix in MATLAB -

i have code in matlab gives me matrix @ end. need take matrix java , use there, when matrix big, hard rewrite element element in java. wrote code in matlab:

function javamatrix = generatejavaformatedmatrix(matrix, name)      i=1:size(matrix,1)         j=1:size(matrix,2)             javamatrix(i,j) = char([name '[' num2str(i-1) ']' '[' num2str(j-1) ']=' num2str(matrix(i,j)) ';' ' '])         end     end end 

which expect trick me, , need copy array , paste in java. example, want above code when write following command:

java_matrix = generatejavaformatedmatrix(eye(3),'a') 

is following

a[0][0]=1; a[0][1]=0; a[0][2]=0; a[1][0]=0; a[1][1]=1; a[1][2]=0; a[2][0]=0; a[2][1]=0; a[2][2]=1; 

however, getting following error:

subscripted assignment dimension mismatch.  error in generatejavaformatedmatrix (line 5)             javamatrix(i,j) = char([name '[' num2str(i-1) ']' '[' num2str(j-1) ']=' num2str(matrix(i,j)) ';' ' ']) 

any highly appreciated.

here code trick.

function s = generatejavaformatedmatrix( a, sigdigs, name ) if nargin < 2     sigdigs = 15; end format  = [ '%+1.', int2str(sigdigs), 'e' ];  s       = sprintf( 'final double [][] %s = {\n', name );  row = 1:size(a,1)     s   = [ s, '    { ' ];     col = 1:size(a,2)         s   = [ s, num2str( a(row,col), format ) ];         if ( col ~= size(a,2) )             s   = [ s, ', ' ];         end     end     if row == size(a,1)         s   = sprintf( [ s, ' } \n' ] );     else          s   = sprintf( [ s, ' }, \n' ] );     end end s   = [ s, '};' ]; 

so example, running command

>> generatejavaformatedmatrix( eye(3), 3, 'a' ): 

will give:

ans =  final double [][] = {     { +1.000e+00, +0.000e+00, +0.000e+00 },      { +0.000e+00, +1.000e+00, +0.000e+00 },      { +0.000e+00, +0.000e+00, +1.000e+00 }  };
