How to draw the values of a comma-separated list with 100 values?

Dear Mathlab Collaborators,

I am trying to draw some information from an struct format unsuccessfully, the software retrieve me this message:

struct with fields:

DT_span: [97×1 datetime]
consumo_cum: [1×1 struct]
tomato_values: [97×1 double]
clima_st: [1×1 struct]
crop_st_2: [1×1 struct]
crop_st: [1×1 struct]
cc_st: [1×1 struct]
PowerH2COM: [97×1 double]
Th: [97×1 double]
subs_st: [1×1 struct]
input_parameters: [1×1 struct]
total: [1×1 struct]

> best_benefit_span.sim.PowerH2COM
Intermediate dot '.' indexing produced a comma-separated list with 100 values, but it must produce a single
value when followed by subsequent indexing operations.

How to deal with this?

Thanks in advance.

can you sahre your structure (mat file) ?

This works for you?

> best_benefit_span

best_benefit_span = 

1×100 struct array with fields:

sim
benefit

Assuming that every field POWERH2COM contains arrays of the same size, and also that every SIM structure contains exactly the same fieldnames.

tmp = [best_benefit_span.sim];
out = [tmp.PowerH2COM] % 97x100 double array

or

out = {tmp.PowerH2COM} % 1x100 cell array of 97x1 double arrays
