Rank Deficient Problem 2.40 An engineer's guide to matlab.
|
| |
Basically i have to find the hoop stress. v1=.4;
v2=.4;
E1=2.1*10^9;
E2=.21*10^9;
U0=.25;
a=5;
b=6.4;
c=8;
k=[1,a^2,0,0;1,b^2,-1,-b^2;-(1 +v1),(1-v1)*b^2,(1+v2)*E1/E2,- (1-v2)*(b^2)*E1/E2;0,0,-(1+v2) ,(1-v2)*c^2]
j=[0;0;0;-U0*E2*c]
[K,J]=meshgrid(k,j)
y=K/J
I should be getting the values with which i am going to calculate the hoop stress, but the values im getting do not make sense. Im getting warning Rank Deficient 1... more »

Z SOURCE INVERTER
|
| |
This project presents an impedance-source (or
impedance-fed) power converter (abbreviated as Z-source converter) and its control method for implementing dc-to-ac, ac-to-dc,
ac-to-ac, and dc-to-dc power conversion. The Z-source converter
employs a unique impedance network (or circuit) to couple the... more »
