Hi, I'm fairly new to coding and I need help with writing a code that automatically creates 2 matrices using input data.

This is the direction im heading in. I'm trying to use an if loop in side of a for loop to go into my MSUP matrix and create an unknown and known displacement matrices

for AA=1:size(MSUP,1)

if MSUP(AA,2)

unknown_displacements=[]; %%

known_displacements=[]; % (1xNR)

endfor

The end result should look like this

unknown_displacements=[6 7 8];

known_displacements=[1 2 3 4 5];

my MSUP looks like this

MSUP=[1 1 1; 3 0 1; 4 0 1]

I need it to go into the MSUP matrix look 1st row tell if (1,2) and (1,3) are 1 or 0. If 1 i need it to add a column to the known displacements matrix and if 0 add it to the unknown matrix

I apologize if this is confusing 1st time posting here
