hi
how I could programming for controlling a dc motor with monster moto shield and Matlab?
I use:
a=arduino('com9','uno');
writeDigitalPin(a,'D7',1);
writeDigitalPin(a,'D8',0);
but nothing happened!
and the dc motor does not run

That code will do nothing. look at https://www.sparkfun.com/products/10182, documents-tab, and look for sample code (download directly or on github) It will be a good starting point

I know that but this code is just for Arduino and its format is PDE but I want to run the motor with Matlab and as the datasheet of the monster moto shield the digital pins 7 and 8 are used to run the dc motor but why it does not work?
Are you inputting the other signals that maybe needed to run the motor or are you expecting D7 and D8 signals alone will run the motor?
Although for Arduino. The example code also shows what other signals are used.

No, I just used D7 and D8 signals
It will not run with only D7 and D8 being used
Other signals are needed to enable the IC’s. I can’t say exactly all that will be needed. As I have no experience with the IC’s or the board. Just what the schematic and data sheet provided.
The enable, PWM determines speed. INA, INB determine which direction the motor runs. According to the data sheet.
The schematic shows some of the signals pulled low by resistors. So they can’t be unconnected and need to be used for a signal input.
I hope you can get someone with actual use of the board to give you more definite information.

ok thank you so much
BLH, thank you so much, you were right it will not run only with D7 and D8 and it needs the speed (PWM D5)
and the correct code is:
a=arduino('com9','uno');
writePWMVoltage(a,'D5',3);
writeDigitalPin(a,'D7',1);
writeDigitalPin(a,'D8',0);
