how can i submit the index for previous matrix in for loop

Hi All,

Please i need a help with this problem.

F_{ii}=F+(M/(B*dt^2))*(u{ii-1}+dt*v{ii-1}+(0.5-B)*dt^2*a{ii-1})+...
C*((A/(B*dt))*u{ii-1}+((A/B)-1)*v{ii-1}+((A/(2*B))-1)*dt*a{ii-1});

How can I submit the index for the previous matrix in for loop

best

Aziz

Sorry, could you explain what you mean by "submit"? And which previous matrix are you referring to ?

[Youssef Khmou]

hi, the index is "ii", but what is the previous matrix ?

[Walter Roberson]

Which previous matrix? The question involves, at the very least, the matrices "F_" and "u" and "v" and "a"

Do the curly braces mean, that the corresponding symbols are cell arrays, or do you use your own notation without explaining the details?
