I need to convert hexadecimal values into signed decimal values,

1. I have a log file(data.log) which contain arrays of(52X1)hexadecimal values.
2. Data is saved like this in the log file

F29E031C

F398031C

F3220376

F2220376........

3. first I need to import these values into the matlab

4. Then i need split this 8 charecter cell into 2 rows (like F29E031C = F29E 031C)

5.Finally i need to convert these values into 16bit signed decimal

(for example:

F29E031C = F29E 031C

convetred -3426 796

)

[Walter Roberson]

 S = 'F29E031C'

S = 'F29E031C'

 typecast(uint16(sscanf(S, '%4x')),'int16')

ans = 2×1

-3426 796

Except replace the assignment to S with

S = fileread('YourFileName.log');

Thank you so much,

But how can I save -3496 and 796 in two different column

as shown in the image.

[Walter Roberson]

 S = 'F29E031C F398031C F3220376 F2220376'

S = 'F29E031C F398031C F3220376 F2220376'

i16_values = typecast(uint16(sscanf(S, '%4x')),'int16')

i16_values = 8×1

-3426 796 -3176 796 -3294 886 -3550 886

two_columns = reshape(i16_values, 2, []).'

two_columns = 4×2

-3426 796 -3176 796 -3294 886 -3550 886
