arm_mat_cholesky_f32 in the CMSIS Library not found in my STM32 Middleware

Hey everyone, I'm working on a project where I'm implementing an algorithm on an STM32H7. As part of the algorithm, I need to compute the square root of a matrix using Cholesky decomposition. I noticed that the CMSIS-DSP library includes a function called arm_mat_cholesky_f32. However, after including CMSIS-DSP through the ioc  (X-ALGO middleware), I can't seem to find this function in my project. Am I missing something here?

Hello @Rayen_Bouafif 

The X-ALGO middleware is based on CMSIS-DSP version 1.8.0. Please note that this version does not provide the arm_mat_cholesky_f32 function, as it was introduced in later releases of the CMSIS-DSP library.

Please check the CMSIS DSP release note for more details.
