Obviously, the A and B indicators need to be 2D arrays. Are they? (what does it tell you if you hover over the broken wire?)

You also did not wire the lower loop correctly. In your case, LabVIEW cannot tell the number of iterations. Do you know why?

[zhako]

yes,A and arrays must be 2d,but minimum elements 1d.Can you fix it?

[altenbach]

Right-click they array indicator...add dimension. (or just grab the index and resize down for two indices.)

Compare with my picture!

(At this point in the learning curve you should not try to be smarter than me and leave out stuff that you think is not needed)

Read the error Details, it tells you exactly what to do.

I. Find the coordinates and the maximum value of the minimum elements
of each column of the matrix. Output:
• the coordinates of the minimum elements of the columns;
• the coordinates and the maximum value.
II. Create and output a one-dimensional array of the products
of the non-zero elements of each column of the matrix. If all the
elements in a column are equal to 0, the corresponding element of the
one-dimensional array should be equal to 0.pls help

Hi zhako,

please show us your own attempts and tell us where you are stuck with your homework!

I'm a newbie and have no idea what to do.

See those Training resources offered in the header of the LabVIEW board.

(And learn to draw program flow charts to visualize what you intend to program…)
