# subject¶

Specifies the subject to study in the postprocessing commands, such as plotting and exporting.

## Syntax¶

subject = index
subject = all
subject = average


where index is a scalar expression evaluating to a positive integer (1-based index into the simulated subjects).

## Description¶

subject = index uses only the subject with index index in the subsequent postprocessing commands.

subject = all uses all subjects in the subsequent postprocessing commands. In plotting commands, this will produce one line per subject.

subject = average will compute the average value of all subjects in the subsequent postprocessing commands. In plotting commands, this will produce one single line, representing the average of all subjects.

## Dependencies¶

• When specified as an index, this index must be $$\ge 1$$ and $$\le n$$ where $$n$$ is the value of n_subjects.

## Examples¶

n_subjects = 10
subject = all


will make the plotting commands render 10 lines, one per subject.

n_subjects = 10
subject = average


will make the plotting commands render one line showing the average of all subjects.

@variables p = 5
n_subjects = 10
subject = p + 1


will make the plotting commands render one line showing the values for subject number 6.
