How to Count Negative Integers in Matrix ?

s=sign(A)

ipositif=sum(s(:)==1)

inegatif=sum(s(:)==-1)

@rashedcs you can run two loops to check every element of the matrix that whether it is less than zero or not.

```
int count=0;
for(int i=0;i<rows;i++){
for(int j=0;j<columns;j++){
if(matrix[i][j]<0)
count++;
}
}
printf("%d",count);
```
