I want to do minimization in CVX, but I got error
minimize norm y-sum(Aixiz) with given x
it means I want to find A but because of practical material I need to calculate " i rows of matrix A " and then do multiplication in i th row of vector x and do it again.
A is a matrix 10025 (unknown)
y is a vector 251(known)
x is a vector 251(known)
z is a vector 251(known)
so as I said I derive A1 by 25 rows of matrix A and then calculate A1xiz and do it four times and then adding them to find sum(Aixiz) at final I want to minimize norm (y- sum(Aixiz) )
I do not know how to implant this in CVX because if I says my variable is A how can I implement it in minimization part ?
I hope this help to know what am I saying and Thanks for help
