Hi,
So my code looks like:
---------------------------------------------------
Air_desnity=[0.646:0.01:1.225];
W_412_MTOW=5534;
A_412=153.93804;
Power_412=(W_412_MTOW*9.81)^3/(2*Air_desnity*A_412).^0.5
--------------------------------------------------------------
And the error is:
Error using /
Matrix dimensions must agree.
Error in Power (line 6)
Power_412=(W_412_MTOW*9.81)^3/(2*Air_desnity*A_412).^0.5
------------------------------------------------------------------------------------------------
Could someone explain what the error means I tried following it and applying the steps but it doesn't make any sense to me

Use element-wise division, so (./) instead of (/) —
Air_desnity=[0.646:0.01:1.225];
W_412_MTOW=5534;
A_412=153.93804;
Power_412=(W_412_MTOW*9.81)^3./(2*Air_desnity*A_412).^0.5
.

In order to perform elementwise division you should use ./ instead of /
Air_desnity=[0.646:0.01:1.225]
W_412_MTOW=5534;
A_412=153.93804;
Power_412=(W_412_MTOW*9.81)^3./(2*Air_desnity*A_412).^0.5
