Im completely new to matlab and I've got a problem that undoubtedly has a simple solution, but its beyond me at the moment, can anyone help?
  • function [m, s1, s2] = Pop_up_test()
  • answer = inputdlg({'mass', 'spring constant 1', 'spring constant 2'},'parameters',1);
  • m = answer(1);
  • disp(m);
  • F = m * 9.8;
  • disp(F)
I get the error in the 5th line where I calculate the force

How to understand this arguments with simple coding??
see matrix W is the adjacency model
so that if you have n variables V={v1 ... vn} then: V=V*W
therefore:
v1={0 v2 v3 v4 ... vn} * W(:,1) which is the first column in W v2={v1 0 v3 v4 ... vn} * W(:,2) which is the second column in W ... vn={v1 v2 v3 v4 ... vn-1 0} * W(:,n) being the nth column in W

I have my data as
filename is 'ofile.xlsx' that contains the following data :
Year Month Day
2014 06 11
2014 05 10
2014 07 15
I am trying to do this
......
....
datecol1 = ofile(:,3)
datecol2 = ofile(:,4)
datecol3 = ofile(:,2)
datecol = datecol1*1000000 + datecol2*10000 + datecol3;
datestr(datecol,'mm/dd/yyyy')
But it does not give output as
06/11/2014
05/10/2014
07/15/2014
Can you tell me what is wrong in this part of my code?
