can anyone please help me converting the code

sbit rd= P3^4;
sbit intr= P3^5;
void delay(unsigned int);

void lcd_data_string(unsigned char*);
void lcd_init();
void adc_conv();
void adc_read();

{
while(1)
{
dataport=0x00;

Answers isn't a free consulting service; looks like a pretty straightforward piece of code that could be translated essentially line-by-line. Having the include file would be needed.
ADDENDUM:
Reading the code a little more -- this is actually addressing some piece of hardware...that'll not be something base MATLAB can do--you'll at a minimum need to have a device driver and likely the Instrumentation TB and whether the device is supported you'd have to find out.
I'd guess the more practical way would be to write a mex function to interface to the C code or just spawn a process to run the code as is...

I’ve had a lot of luck translating C code line by line. After I get that working, I go back and hand optimize the code (Loop in particular are ripe for optimization). I don’t know of any automated ways to do this. You should expect your MATLAB to not run as fast as compiled C code.
