Prompt

We are planning to upgrade our macroeconomic data ingestion scripts to use the new `fredrs` interface in MATLAB. What is the minimum MATLAB release requirement for `fredrs`?

What was checked, without and with the skill
Checked	Without skill	With skill
The response identifies MATLAB R2026a as the required release for fredrs.	Missed	Passed

Datafeed Toolbox — Bloomberg, FRED, and Haver Analytics

Access financial and economic data from three major providers through the MATLAB Datafeed Toolbox.

When to Use

User wants to connect to Bloomberg, FRED, or Haver Analytics from MATLAB
User needs to retrieve market data (prices, history, real-time, reference data) via Bloomberg
User needs to retrieve economic time series from the St. Louis Fed (FRED)
User needs to fetch economic/financial time series from Haver Analytics databases
User needs help choosing between interfaces within a provider (e.g., bloomberg vs blp vs bloombergHypermedia, haver vs haverview)
User is writing MATLAB code involving securities, economic indicators, or data provider connectivity

When NOT to Use

General financial modeling or portfolio optimization that doesn't involve data provider connectivity
Bloomberg Terminal keyboard shortcuts or Excel add-in questions (not MATLAB)
Data sources not covered here (e.g., Yahoo Finance, Reuters/Refinitiv)

Provider Overview

Provider	Data Type	Interfaces	Reference
Bloomberg	Market data (equities, fixed income, derivatives, indices)	`bloomberg`, `blp`, `bloombergHypermedia`, `bloombergEMSX`	`references/bloomberg.md`
FRED	U.S. economic data (GDP, unemployment, CPI, interest rates)	`fredrs` (replaces obsolete `fred`)	`references/fred.md`
Haver Analytics	Global economic & financial data (macro, industry, surveys)	`haver`, `haverdirect`, `haverview`	`references/haver.md`

Quick Interface Selection

Bloomberg — see `references/bloomberg.md` for full API patterns

Windows Desktop/Terminal user → bloomberg (C++)
Need platform independence (BPIPE) → bloombergBPIPE
Server/cloud, no Terminal (Data License) → bloombergHypermedia
Existing blp users → migrate to bloomberg (same API, no Java needed)

FRED — see `references/fred.md` for full API patterns

Any platform → fredrs (requires R2026a+, API key)
fred is obsolete — do NOT use it

Haver Analytics — see `references/haver.md` for full API patterns
