Matrix Operations - Page 1

Sorry for writing in English, but I dont know if you would understand my French.

If I have:

mat1=[12345]
[67890]
[11121]
[14151]

I can get the second line with mat1[2] but how do i get the second column?

Thanks to everyone for this great forum

PS:
You can answer in French.

on Ti , a Matrix Syntaxe is mat = [[Row1][Row2]...];
to get a row :
: MatrixName[RowNum]
to get a Column
:subMat( MatrixName,numRow1,NumCol1,NumRow2,numCol2)

Thank you very much andoh_wilfried, thats exactly what i wanted!

or
: MatrixName^T[ColNum]

Thanks for the answer bobti89.
Thats the method I was using before, but for a very big matrix, I find it a bit slower than the 'subMat' method.

I suppose AMS actually computes the transposed matrix with the second method.

Yes, complex numbers are modified (according to the manual, anyway)
