Pre allocate outputs

pre_allocate_outputs

Syntax

matlab function process_flags = pre_allocate_outputs(input_files, tag)

Description

pre_allocate_outputs creates placeholder MAT-files for chunked processing and reports which batches still need work. For traditional inputs it simply checks whether the derived output file exists; for chunked runs it creates the destination datasets at the proper size using matfile so downstream steps can stream results directly to disk.

Function Inputs

Parameter Name	Type	Description
input_files	cell	Elements are either raw filenames or chunk descriptors produced by create_batch_list.
tag	char	Suffix appended to output filenames (e.g. '_mc', '_det').

Function Outputs

Name	Type	Description
process_flags	logical array	Logical mask indicating which entries require processing (true) versus already-complete batches (false).

Example Usage

```matlab input_files = create_batch_list(opt.input_files, opt.batch_sz, '_det'); process_flags = pre_allocate_outputs(input_files, '_det');

for k = find(process_flags) Y = CaliAli_load(input_files{k}, 'Y'); % ... process chunk ... CaliAli_save(input_files{k}(:), Y, CaliAli_options); end ```
