How to write a mixed data (number and {real, imag}) in a CSV file ?

I need to write a CSV file with matrix in the first column and {real, imag} in the second column.

Example

matrix1 = {10;20;30};

matrix2 = [ { 2.3027900000000e-03, 2.0292300000000e-11};{ 8.6489600000000e-03, 1.7520000000000e-03};{ 8.5228400000000e-03, 7.1978700000000e-04}];

CSV file output as:

10 { 2.3027900000000e-03, 2.0292300000000e-11}

20 { 8.6489600000000e-03, 1.7520000000000e-03}

30 { 8.5228400000000e-03, 7.1978700000000e-04}

The second is real and imag value in curly brackets with a comma. I need this format to replace the data in a pyhond code.

Thanks!

Does this work for you?

matrix1 = {10;20;30};
matrix2 = [ {  2.3027900000000e-03,  2.0292300000000e-11};{  8.6489600000000e-03,  1.7520000000000e-03};{  8.5228400000000e-03,  7.1978700000000e-04}];

C = [matrix1 compose('{%e, %e}',reshape([matrix2{:}],size(matrix2)))];
writecell(C,'csv_file.csv')

If not, please upload a sample csv file that has the required format.

Thank you.

The compose command works!
