Re: [Gretl-users] matrix declaration error

Hi Sven thanx for your quick response. but err... It does not work too... In fact what is puzzling is that i changed the code because the ER1, ER2, ER3 are actually scalars. So I changed the code to declare them as scalars, then as can be seen i show them again (to check they are correctly defined and accessible), so that i build the matrix ER = {ER1;ER2;ER3} from them but gretel says they are undefined. Now I change the code so that they are computed as matrices, so that i can use your advice by concatenating them later... drums sounding... ooouch... does not work : ======================================================= # elasticities standard errors matrices ? matrix EP={EP11,EP12,EP13;EP21,EP22,EP23;EP31,EP32,EP33} Replaced matrix 'EP' ? matrix EP EP 0.0095979 0.0065156 0.0068756 0.028839 0.019577 0.020659 0.0015852 0.0010761 0.0011356 ? matrix ER = (ER1 ~ ER2 ~ ER3)' Error adding matrix 'ER' Error executing script: halting > matrix ER = (ER1 ~ ER2 ~ ER3)' =========================================== The problem is still there : matrix EP is correctly built but not ER. The elements of both are still accessible elsewhere... Well, help very welcome ! cheers Franck
