Creating vectors using variables as endpoints
显示 更早的评论
When attempting to create a vector 't' using the following code:
for t = RSLT.lag_min+1:RSLT.date_ct;
I receive the following error:
Error using :
Colon operands must be in the range of the data type.
RSLT is a 1x1 structwith 18 fields (lag_min and date_ct being among them). Is it feasible to create vector using two variables?

What data type (class) are RSLT.lag_min and RSLT.date_ct? Your syntax should work for most, but I'm guessing perhaps your endpoints are different classes that are perhaps not compatible when one is recast to the other.

In MATLAB, if you want to use a structure called RSLT that has fields .lag_min and .date_ct first define them like RSLT.lag_min=1 RSLT.date_ct=2
The error message you receive is regarding the . used in MATLAB as element wise to whatever operator preceding.
For instance
A=randi(10,4,4)
A =
2 1 5 2
2 10 4 8
3 10 10 4
5 5 4 3
B=randi([-5 5],4,4)
B =
-1 5 -2 -4
-4 1 4 2
-4 -5 -5 3
5 -3 -5 2
A*B
=
-16 -20 -35 13
-18 -24 -24 40
-63 -37 -36 46
-26 1 -25 8
A.*B
=
-2 5 -10 -8
-8 10 16 16
-12 -50 -50 12
25 -15 -20 6
I applies to all basic operations .+ .- .* and ./
