The value 1 shows up on index 0 4 6 and 9 so the plot will have an x axis 1 10 and will only show a spike in the y direction when there is a value of 1 in the array. X 1 10 1 3 5 7 9 11 13 15 17 19 k find x 13 k 7 to find a noninteger value use a tolerance value based on your data.

Use logical indexing with a simple assignment statement to replace the values in an array that meet a condition. Rounding type specified as decimals or significant the rounding type determines whether round considers digits in relation to the decimal point or the overall number of significant digits n must be a positive integer when you specify significant in that case the round function rounds to the nearest number with n significant digits. Round towards minus infinity. I know how to do with a certain column by using find like.

To iterate over the values of a single column vector first transpose it to create a. So for the above array i want to plot for only value 1 occurrence. To find a specific integer value use the operator. For instance find the element equal to 13 in a 1 by 10 vector of odd integers.

To programmatically exit the loop use a break statement. To skip the rest of the instructions in the loop and begin the next iteration use a continue statement. Y floor t rounds each element. Run the command by entering it in the matlab command window.

The for statement overrides any changes made to index within the loop. First if you want to round down for a positive and a negative number you can use the matlab function floor. Matlab treats the array as a single column vector with each. Sometimes it is useful to simultaneously change the values of several existing array elements.

But here i need to find such rows for all columns and the number of column is huge. I want to plot only say value 1 from this array in accordance with the index in which the value resides in. Hi there say i have an array 1 3 5 7 1 5 1 7 8 1. Round down in matlab.

Round each value in a duration array to the nearest number of seconds less than or equal to that value. For each column i want to get the rows which has a certain value let s say 1. Web browsers do not support matlab commands.
