If you have any questions, please reply me.This Code is written in the MATLAB language and requires some modifications to run in the Code Composer Studio(CCS) because CCS mainly supports C and assembly language. The following changes are required:

Declare variables, for example:

```
float Saf[3] = {a, b, c};
float Sbt[3] = {d, e, f};
float uaf, ubt, fp1, fp2, fp3, t1, t2, t3;
```

1. Replace MATLAB's matrix index(e.g. Saf(1)) with C's array index(e.g. Saf[0]).

2. Replace the multiplication symbol of MATLAB( @) with the multiplication symbol of C language(*).

3. Use M_PI macro definition in math.h library instead of pi constant in MATLAB.

The modified code is as follows:

```
#include
```
float Saf[3] = {a, b, c};
float Sbt[3] = {d, e, f};
float uaf, ubt, fp1, fp2, fp3, t1, t2, t3;
uaf = Saf[0];
ubt = Sbt[0];
fp1 = 2 * 5 * M_PI * uaf + 2 * 50 * M_PI * ubt;
uaf = Saf[1];
ubt = Sbt[1];
fp2 = 2 * 50 * M_PI * uaf + 2 * 50 * M_PI * ubt;
uaf = Saf[2];
ubt = Sbt[2];
fp3 = 2 * 50 * M_PI * uaf + 2 * 50 * M_PI * ubt;
t1 = fp1 + fp2 + fp3;
t2 = fp1 + fp2 - fp3;
t3 = 1 - t1 - t2;

Note that you need to add #include < at the beginning of the program; math.h> To include the math.h library file. If you need to put this code into a CCS DSP program, you also need to pay attention to issues such as floating point precision and memory management.
