Hi,
Is there a way in Matlab to perform a t-test using only averages and standard deviations that I read from a file? I dont have the original data.

You need one more item of data to calculate a t-statistic: the number of observations that went into the calculation of each mean and standard deviation. See Student’s t-test for details. The t-distribution approximates the normal distribution if the number of observations is greater than 30.
